A liquid mixture composed of 20% CH4, 30% C2H4, 35% C2H2, and 15% C2H2O. What is the average molecular weight of the mixture?(a) 20(b) 25(c) 6.75(d) 9.25This question was posed to me during an internship interview.This is a very interesting question from Analyses of Multicomponent Solutions and Mixtures in portion Moles, Density & Concentration of Basic Chemical Engineering

Answer»

The CORRECT ANSWER is (b) 25

For explanation: Since it is a liquid mixture so the percentages are by WEIGHT, => average molecular weight of mixture = (20 + 30 + 35 + 15)/4 =25.
