A mixture contains 21.7 g NaCI, 3.74 g KCI, and 9.76 g Lici. What is the mole fraction of NaCl in this mixture?
Molar mass
NaCl: 58.44g/mol
KCl: 74.55g/mol
LiCl: 42.39g/mol
Answer:Mole Fraction of NaCl=0.5697
Explanation:
No OF Moles of NaCl= Mass / Molar mass
=21.7 g/58.44g/mol
=0.371moles
No OF Moles of KCl= Mass / Molar mass
=3.74g/74.55g/mol
=0.0502moles
No OF Moles of LiCl= Mass / Molar mass
=9.76 g/42.39g/mol
=0.230moles
Mole Fraction of NaCL = Moles of NaCL/ Total number of moles of the mixture
=0.371/( 0.371+ 0.0502+0.230)
0.371/0.6512
=0.5697
Answer:
Mole fraction: 0.570
Explanation:
Mole fraction is defined as the ratio of moles of a compound in a mixture over the total moles of the mixture. To solve this problem, we need to find moles of the 3 salts:
Moles NaCl -Molar mass: 58.44g/mol-:
21.7g NaCl * (1mol / 58.44g) = 0.3713 moles
Moles KCl -Molar mass: 74.55g/mol-:
3.74g KCl * (1mol / 74.55g) = 0.0502 moles
Moles LiCl -Molar mass: 42.394g/mol-:
9.76g LiCl * (1mol / 42.394g) = 0.2302 moles
Mole fraction NaCl:
0.3713mol / (0.3713mol + 0.0502mol + 0.2302mol) =
0.570

how many atoms are there in 8.08 moles of carbon dioxide
Answer:
145.97×10²³ atoms
Explanation:
Given data:
Number of moles of CO₂ = 8.08 mol
Number of atoms of CO₂ = ?
Solution:
1 mole of CO₂ contain 1 mole C atom.
8.08 mole contain 8.08× 1 = 8.08 mole of C atom.
1 mole of CO₂ contain 2 moles of O atom.
8.08mole contain 8.08×2 = 16.16 mole of O atom.
Total number of moles of atoms = 8.08 mole + 16.16 mole
Total number of moles of atoms = 24.24 mol
Number of atoms of CO₂:
1 mole of any substance contain 6.022×10²³ atoms.
24.24 mol ×6.022×10²³ atoms / 1 mol

What is the formula for Iron (III) Bromate
Answer:
[tex]\boxed {\boxed {\sf FeBr_3}}[/tex]
Explanation:
We can assume that this is a neutral compound, meaning the charges of the ions are balanced.
We are given: Iron (III) Bromide.
We want to find the chemical formula.
First, find the symbols of the elements.
Fe: Iron Br: BromineNext, find the charges on the ions.
The Roman Numeral 3 in parentheses (III). This indicates the iron cation has a charge of +3.
We need to balance out the charge of +3 with the bromine. Bromine can have a charge of +5, +1, and -1. Since we already have a cation (positive ion), bromine must be an anion (negative ion). We also know the charge must be negative to balance out the compound.
But, the charge is only -1. That would still leave the compound unbalanced. Therefore, we must have 3 bromine atoms to balance out the iron. The 3 will become a subscript.
So, put all the information together and write the formula:
FeBr₃
A chemical formula lists the constituent elements of a compound together with the number of atoms in each element's smallest unit, such as a molecule or formula unit. Here the formula for Iron (III) Bromate is FeBr₃.
A compound's chemical composition is symbolically represented by its chemical formula. Chemical formulas reveal the elements that make up a compound's molecules as well as the ratio in which their atoms combine to create those molecules.
The sorts of atoms and their numbers in an element or compound are described by a chemical formula. Each element's atoms are denoted by one or two distinct letters. a collection of chemical symbols indicating the constituent elements and their corresponding ratios.

Kilograms are the largest unit among the options listed.
The metric system is a decimal-based system of measurement widely used around the world. It provides a standardized and convenient way to express measurements by utilizing prefixes that represent powers of 10.
In the metric system, the base unit for measuring mass is the gram (g). The gram is a relatively small unit, and to express larger or smaller masses, prefixes are added to the base unit. Here are some commonly used metric prefixes for mass.
The largest measurement among the options provided is kilograms (kg). Kilograms are larger units of measurement compared to grams (g), milligrams (mg), and centigrams (cg). The metric system follows a decimal-based system, where each unit is 10 times larger or smaller than the adjacent unit.
1 kilogram (kg) is equal to 1,000 grams (g), 1,000,000 milligrams (mg), and 10,000 centigrams (cg). Therefore, kilograms are the largest unit among the options listed.

B. A force created by similarities in electronegativity and the small size of the hydrogen atom
make them especially strong,
C. Forces created by temporary dipoles that result from the movement of electrons in non-
polar molecules.
D. A force created by differences in electronegativity and the large size of the hydrogen atom
make them especially strong,
E. The force between polar molecules when the opposite partial charges of a molecule exert a
force on each other
Answer:
A hydrogen bond is an intermolecular force (IMF) that forms a special type of dipole-dipole attraction when a hydrogen atom bonded to a strongly electronegative atom exists in the vicinity of another electronegative atom with a lone pair of electrons. Intermolecular forces (IMFs) occur between molecules. Other examples include ordinary dipole-dipole interactions and dispersion forces. Hydrogen bonds are are generally stronger than ordinary dipole-dipole and dispersion forces, but weaker than true covalent and ionic bonds.

How many grams are there in 2.34x10^23 atoms of Cu?
The mass of the 2.34 × 10²³ atoms of copper is equal to 24.68 grams.
What is Avogadro's number?The Avogadro constant can be defined as the proportionality factor that the number of constituent particles in a sample with the amount of substance.
Avogadro’s number can be described as a dimensionless number that represents the number of entities in one mole of any substance. These elementary entities can be molecules, atoms, ions, electrons, or protons, etc.
Avogadro’s constant has a value approximately equal to 6.022 × 10²³ mol⁻¹.
Given, the number of atoms of copper = 2.34 × 10²³
The atomic mass of Cu Copper = 63.5 g/mol
So 6.022 × 10²³ atoms of Cu have mass = 63.5 g
Then 2.34 × 10²³ Cu atoms will have mass = [tex]\frac{63.5 \times 2.34 \times 10^{23}}{6.02 \times 10^{23}}[/tex] = 24.68 g
Therefore, 24.68 grams of Cu are there in 2.34 × 10²³ atoms of Cu.

a metal worker uses a cutting torch that operates by reacting acetylene gas, C2H2(g), with oxygen gas, O2(g), as shown in the unbalanced equation below: C2H2(g)=O2(g)= CO2(g) = H2O(g) = heat determine the mass of 25 moles of acetylene (gram-formula mass = 26 g/mol
Answer:
650 grams
Explanation:
Given that acetylene gas reacts with oxygen to produce caobon dioxide, water and heat and the unbalnced equation is
[tex]C_2H_2(g)+O_2(g) \rightarrow CO_2(g) + H_2O(g)+ heat[/tex]
Gram-formula mass of [tex]C_2H_2= 26[/tex] g/mol
So, mass of 1 mole of acelylene is 26 grams
Therefore, mass of 25 moles of acelylene=25x26=650 grams
Hence, the mass of 25 moles of acelylene is 650 grams
The mass of 25 moles of acetylene has been 0.65 kg.
Moles are the count of a number of molecules in an entity and the mass based on the formula mass. 1 mole of a substance has [tex]\rm 6.023\;\times\;10^2^3[/tex] molecules.
The moles can be calculated as:
Moles = [tex]\rm \dfrac{weight}{molecular\;weight}[/tex]
Given, mole of acetylene = 25 mol
molecular mass of acetylene = 26 g/mol
Mass of acetylene = moles [tex]\times[/tex] molecular weight
Mass of acetylene = 25 [tex]\times[/tex] 26
Mass of acetylene = 650 grams
1000 grams = 1 kg
650 grams = 0.65 kg.
The mass of 25 moles of acetylene has been 0.65 kg.

Potasyum-40 küçük atom numaralı doğal radyoaktif birkaç element izotopundan biridir ve doğada K izotopları içerisindeki bolluk yüzdesi %0,012'dir. 1,65 mg K/mL içeren bir bardak sütü içtiğiniz zaman kaç tane 40K atomu yutmuş olursunuz? (1 Bardak süt 225 mL, K: 39,10 g/mol)
Answer:
6.707 × 10¹⁷
Explanation:
From the information given:
40 ^ K kütlesi = sütteki K kütlesi × 40 ^ K / 100 kütle yüzdesi
nerede;
sütteki K kütlesi = 1.65 mg of K/mL × 225 mL = 371.25 mg of K
∴
40 ^ K kütlesi = 371.25 × 0.012/100
40 ^ K kütlesi = 0,04455 mg = 4.455 × 10⁻⁵ grams
40 ^ K mol sayısı = 40 ^ K kütlesi / molar kütle
= 4.455 × 10⁻⁵/40
= 1.11375 × 10⁻⁶
Son olarak, 40 ^ K = mol × Avogadro sayısı atomları
= 1.11375 × 10⁻⁶ × 6.022 × 10^23
= 6.707 × 10¹⁷
