Answer:

The molar solubility of nitrogen gas is $1.32\times 10^{-3}mol/L$ .

Explanation:

Henry's law states that the amount of gas dissolved or molar solubility of gas is directly proportional to the partial pressure of the liquid.

To calculate the molar solubility, we use the equation given by Henry's law, which is:

$C_{N_2}=K_H\times p_{liquid}$

where,

$K_H$ = Henry's constant = $6.26\times 10^{-4}mol/L.atm$

$p_{N_2}$ = partial pressure of nitrogen gas

Total air pressure = P = 2.71 atm

Percentage of nitrogen in air = 78.09%

Mole fraction of nitrogen , $\hi_{N_2}= 0.7809$

$p_{N_2}=P\times \chi_{N_2}=2.71 atm\times 0.7809$

Putting values in above equation, we get:

$C_{N_2}=6.26\times 10^{-4}mol/L.atm\times 2.71 atm\times 0.7809\\\\C_{N_2}=1.32\times 10^{-3}mol/L$

Hence, the molar solubility of nitrogen gas is $1.32\times 10^{-3}mol/L$ .

Write balanced equations and expressions for ksp for the dissolution of each of the following ionic compounds. Write a balanced

Lina20 [59]

Based on the dissolution equation of BaSO4, the solubility product, Ksp, expression of BaSO4 is: [Ba^{2+}] × [SO4^{2-}]

<h3>What is solubility product Ksp of a solute?</h3>

The solubility product, Ksp, of a substance is an equilibrium constant which expresses the product of the concentration of ions produced by a solute.

The solubility of a solute depends on temperature, thus solubility product also depends on temperature.

The balanced equation for the dissolution of barium sulfate is given below:

BaSO4 ⇌ Ba^{2+} + SO4^{2-}

The solubility product for barium sulfate is given as;

Ksp = [Ba^{2+}] × [SO4^{2-}]

Therefore, the solubility product, Ksp, expression of BaSO4 is: [Ba^{2+}] × [SO4^{2-}]
