Question

A gas mixture contains 20% CO, 30% SO2, and 50% N2, if the partial pressure of N2 is 5 atm at 27^oC, what is the molar volume of N2?

(a) 2.4 liter

(b) 3.7 liter

(c) 4.9 liter

(d) 5.6 liter

The question was posed to me by my college professor while I was bunking the class.

Origin of the question is Ideal Gas Mixtures and Partial Pressure in chapter Recycle, Bypass, Purge, Ideal Gases and Real Gases of Basic Chemical Engineering

Answer 1

Right answer is (a) 2.4 liter

The best I can explain: Total pressure of mixture = 5/0.5 = 10 atm, => Molar Volume of N2 = Total molar volume of mixture = 0.0821*300/10 = 2.4 liter.
