Question

A mixture of Kr, N2 and Cl2 has a pressure of 7.85 atm. If the Kr has a mole fraction of 0.47 and N2 has a mole fraction of 0.23, what is the partial pressure of Cl2?

Answer 1

Answer:

$2.4\text{ atm}$

Explanation:

Here, we want to get the partial pressure of the chlorine gas

The total mole fraction is 1

The total mole fraction is the sum of the individual mole fractions

To get the mole fraction of chlorine, we have it that:

$\text{Mole fraction of chlorine = 1-0.47-0.23 = 0.30 mole}$

The partial pressure is the product of the mole fraction and the total pressure

Mathematically, that would be:

$7.85\text{ atm }\times\text{ 0.30 = 2.4 atm}$
