Question

What is the total pressure of contained if it contains 0.5 fraction of O2 with partial pressure 3 Pa, 0.3 fraction of H2 with partial pressure 5 Pa, 0.2 fraction of CO2 with partial pressure 15 Pa?

(a) 6 Pa

(b) 7 Pa

(c) 8 Pa

(d) 9 Pa

The question was asked during an online exam.

Question is from Ideal Gas Mixtures and Partial Pressure topic in portion Recycle, Bypass, Purge, Ideal Gases and Real Gases of Basic Chemical Engineering

Answer 1

The correct choice is (a) 6 Pa

For explanation I would say: Total pressure = 0.5*3 + 0.3*5 + 0.2*15 = 6 Pa.
