(b) 150%

(c) 200%

(d) 300%

I had been asked this question in exam.

I need to ask this question from Material Balance Problems Involving Partial Saturation topic in division Two Phase Gas – Liquid Systems, Phase Rule and Vapor-Liquid Equilibria of Basic Chemical Engineering

Answer 1

Correct option is (b) 150%

Best explanation: Moles of bone dry air = 6, moles of H2O produced = 9, => humidity = 9/6*100 = 150%.
