Answer:
0.355L
Explanation:
1fl oz (Fluid ounce) is an unit of volume widely used in United States of America. 1fl oz is equivalent to 29.5735mL.
12.0 fl oz are:
12.0fl oz * (29.5735mL / 1fl oz) = 354.9mL
There are 354.9mL in 12.0 fl oz.
As 1L = 1000mL, in 354.9mL you have:
354.9mL * (1L / 1000mL =
0.355Lthe bond between which two atoms is most polar

1.004 mol Arsenic is how many atoms?
Answer: [tex]6.047\times 10^{23}[/tex] atoms in 1.004 mol of arsenic
Explanation:
According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number [tex]6.023\times 10^{23}[/tex] of particles.
To calculate the atoms, we use the equation:
[tex]\text{Number of moles}=\frac{\text{Given atoms}}{\text {avogadro's number}}[/tex]
[tex]1.004=\frac{x}{6.023\times 10^{23}}[/tex]
[tex]x=1.004\times 6.023\times 10^{23}=6.047\times 10^{23}[/tex]
Thus there are [tex]6.047\times 10^{23}[/tex] atoms in 1.004 mol of arsenic

1. 55 grams of salt are added to 100 L of water to make a saline solution.
What is the g/L concentration of the aqueous solution?
Show your work!
Answer:
0.55g/L
Explanation:
Given parameters;
Mass of salt = 55g
Volume of water = 100L
Unknown:
g/L concentration = ?
Solution:
To solve this problem, we must understand that concentration is the amount of solute per solution
g/L concentration = [tex]\frac{55}{100}[/tex] = 0.55g/L
How does the number of molecules in 1 mol of oxygen compare with the number of molecules in 1 mol of nitrogen?
1 mol of oxygen has fewer molecules.
1 mol of oxygen has more molecules.
Each sample has the same number of molecules.
The molecules cannot be compared without knowing the mass.
Answer:
Each sample has the same number of molecules.
Explanation:
Just took the quiz on edge 2021
Taking into account the definition of Avogadro's number, each sample has the same number of molecules.
Avogadro's NumberAvogadro's Number or Avogadro's Constant is called the number of particles that make up a substance (usually atoms or molecules) and that can be found in the amount of one mole of said substance. Its value is 6.023×10²³ particles per mole.
Avogadro's number applies to any substance.
This caseAvogadro's number applies to any substance. This means that the number of molecules in 1 mol of oxygen is equal to the number of molecules in 1 mol of nitrogen.
Finally, the correct answer is the third option: each sample has the same number of molecules.

How many grams are in 3.00 x 10^24 molecules of Zn(C2H3O2)2?
Answer:
Mass = 917.4 g
Explanation:
Given data:
Number of molecules = 3.00 ×10²⁴ molecules
Mass in gram = ?
Solution:
1 mole contain 6.022 × 10²³ molecules
3.00 ×10²⁴ molecules × 1 mol / 6.022 × 10²³ molecules
0.5×10¹ mol
5 mol
Mass in gram:
Mass = number of moles × molar mass
Mass = 5 mol × 183.48 g/mol
Mass = 917.4 g

a sample of methane gas at a pressure of 0.727 atm and a temperature of 26.9 occupies a volume of 726 ml. if the gas is allowed to expand at constant temperature until its pressure is 0.412 atm, the volume of the gas sample will be _ mL
Answer:
1280L
Explanation:
Given parameters:
Initial pressure = 0.727atm
Temperature = 26.9°C
Initial volume = 726mL = 0.726L
New pressure = 0.412atm
Unknown:
New volume of the gas sample = ?
Solution:
To solve this problem, we apply boyles law;
P1V1 = P2V2
P and V are pressure and temperature
1 and 2 are initial and new state
0.727 x 0.726 = 0.412 x V2
V2 = 1.28mL = 1280L

Animals get carbon from plants.
B.
Plants take carbon from the soil.
C.
Photosynthesis uses carbon monoxide.
D.
Animals take carbon from the atmosphere.
E.
Plants take carbon from the atmosphere.
Answer:
E) Plants take carbon from the atmosphere
Explanation:
Plants are a vital part in keeping the air clean. They take in CO2, H2O, and sunlight to start processing photosynthesis. The carbon taken in by the plant still remains with it after it dies, thus, fossil fuels.

Calculate the molar mass of NaNO3-
If the [H+] of a solution is 6.8 x 10-9 mol/L the pH is
Answer:
8.2
Explanation:
To solve this problem;
The concentration of [H⁺] = 6.8 x 10⁻⁹mol/L
So, we need to convert this to pH:
pH = -log [H⁺]
So;
pH = -log 6.8 x 10⁻⁹ = 8.2

To see the number of atoms of an element in a given molecule we need to multiply stoichiometry to the number that is written on the foot of the element that is stoichiometry. Therefore, the correct option is option A.
What is atom?
Atom is the smallest particle of any element, molecule or compound. Atom can not be further divided. Atoms contains nucleus in its center and electron that revolve around the atom in fixed orbit.
In the nucleus, proton and neutron are present. Electron has -1 charge while proton has +1 charge. Neutron is neutral that is it has no charge. So overall the charge of nucleus is due to only proton, not by neutron. Most atoms are bonded together to make a molecule. Molecules combine to form compounds.
Therefore, the correct option is option A.
