Explanation:

Answer: 1.461 g of NaCl is dissolved in the solution.

Explanation:

Molarity is defined as the amount of solute expressed in the number of moles present per liter of solution. The units of molarity are mol/L.

The formula used to calculate molarity:

[tex]\text{Molarity of solution}=\frac{\text{Given mass of solute}\times 1000}{\text{Given mass of solute}\times \text{Volume of solution (mL)}}[/tex]       .....(1)

Given values:

Molarity of solution = 0.050 M

Molar mass of NaCl = 58.44 g/mol

Volume of solution = 500.0 mL

Putting values in equation 1, we get:

[tex]0.050=\frac{\text{Given mass of NaCl}\times 1000}{58.44\times 500}\\\\\text{Given mass of NaCl}=\frac{0.050\times 58.44\times 500}{1000}\\\\\text{Given mass of NaCl}=1.461g[/tex]

Hence, 1.461 g of NaCl is dissolved in the solution.

Just add a plenty of dots in the first one and very few dots in the second one

An area with high population density will have many dots while areas will low population density will have few dots when using dots to illustrate population density.

Population density is the ratio of the total number of organisms found in a given area to the total of the area of that place or habitat.

An area with high population density indicates that more organised ate found per unit area than an area with low population density.

Therefore, using dots to illustrate population density, an area with high population density will have plenty dots while areas will low population density will have few dots scattered over.

Answer:

Percent Yield = 80%

Explanation:

Percent yield of a reaction is defined as one hundred times the ratio between the actual yield and the theoretical yield. That is:

Percent yield = Actual Yield / Theoretical Yield * 100

Where theoretical yield of CaHPO4 is 10g and actual yield is 8g

Replacing:

Percent yield = 8g / 10g * 100

The salt produced in the neutralization reaction between NH₄OH and HNO₃ is NH₄NO₃ (ammonium nitrate).

A neutralization reaction is a reaction between an acid and a base to form salt and water. The cation of the salt will come from the base while its anion will come from the acid.

Let's consider the neutralization reaction between NH₄OH and HNO₃. The formed salt will be ammonium nitrate.

NH₄OH + HNO₃ ⇒ NH₄NO₃ + H₂O

The salt produced in the neutralization reaction between NH₄OH and HNO₃ is NH₄NO₃ (ammonium nitrate).

Answer:

TRUE!!!!

Explanation:

Water can act as both an acid and a base in solution and undergoes autoionization, where it can be both an acid and a base to itself. When mixed with an acid, water accepts hydrogen ions and acts as a base. However, when water is mixed with a base, it donates hydrogen ions and acts like an acid.

Explanation:

Applying,

R = R'[tex]2^{n/t}[/tex]................... Equation 1

Where R = original sample of radon-222, R' = sample of radon-222 left after decay, n = Total time, t = half-life.

make R' the subject of the equation

R' = R/([tex]2^{n/t}[/tex])............... Equation 2

From the question,

Given: R = 73.9 g, n = 23 days, t = 3.8 days.

Substitute these values into equation 2

R' = 73.9/([tex]2^{23/3.8}[/tex])

R' = 73.9/[tex]2^{6.05}[/tex]

R' = 1.115 g

Answer: The molality of [tex]MgF_2[/tex] solution is 4.013 m

Explanation:

Molality is defined as the amount of solute expressed in the number of moles present per kilogram of solvent. The units of molarity are mol/kg.

The formula used to calculate molarity:

     .....(1)

Given values:

Given mass of [tex]MgF_2[/tex] = 20.0 g

Molar mass of = 62.3 g/mol

Mass of solvent = 80.0 g

Putting values in equation 1, we get:

[tex]\text{Molality of }MgF_2=\frac{20.0\times 1000}{62.3\times 80.0}\\\\\text{Molality of }MgF_2=4.013m[/tex]

Hence, the molality of [tex]MgF_2[/tex] solution is 4.013 m

Answer:

For 2: The % yield of the product is 92.34 %

For 3: 12.208 L of carbon dioxide will be formed.

Explanation:

The percent yield of a reaction is calculated by using an equation:

[tex]\% \text{yield}=\frac{\text{Actual value}}{\text{Theoretical value}}\times 100[/tex]              ......(1)

Given values:

Actual value of the product = 78.4 g

Theoretical value of the product = 84.9 g

Plugging values in equation 1:

[tex]\% \text{yield}=\frac{78.4 g}{84.9g}\times 100\\\\\% \text{yield}=92.34\%[/tex]

Hence, the % yield of the product is 92.34 %

The number of moles is defined as the ratio of the mass of a substance to its molar mass.

The equation used is:

[tex]\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}[/tex] ......(2)

Given mass of carbon dioxide = 24 g

Molar mass of carbon dioxide = 44 g/mol

Plugging values in equation 1:

[tex]\text{Moles of carbon dioxide}=\frac{24g}{44g/mol}=0.545 mol[/tex]

At STP conditions:

1 mole of a gas occupies 22.4 L of volume

So, 0.545 moles of carbon dioxide will occupy = [tex]\frac{22.4L}{1mol}\times 0.545mol=12.208L[/tex] of volume

Hence, 12.208 L of carbon dioxide will be formed.

Answer:

6.62 × 10²⁴

Explanation:

wanna have fun?

The number of NaCl present in the 11 moles is equal to 6.62 × 10²⁴ NaCl. Therefore, option (C) is correct.

Avogadro’s number is used to express the number of entities in one mole of a chemical substance. Generally, these entities can be ions, molecules, atoms, electrons, or protons, which depends upon the type of chemical reaction.

The value of Avogadro’s constant is experimentally found approximately equal to 6.022 × 10²³ mol⁻¹.

Given, the number of moles of the NaCl =  11.0 mol

The molar mass of the NaCl = 23 +  35.5 = 58.5 g/mol

One mole of NaCl has formula units of NaCl =  6.022 × 10²³

Then 11 moles of  NaCl have formula units of NaCl = 11 × 6.022 × 10²³

                                                                                =  6.62 × 10²⁴ NaCl

Therefore,6.62 × 10²⁴ formula units of NaCl are present in 11 moles of NaCl.
