QUESTION:

If 100 lbm/min of A (MA 2) and 300 lbm/min of B (MB 3) flow through a pipe, what are the mass fractions and mole fractions of A and B, the mass flow rate of A, the molar flow rate of B, the total mass flow rate, and the total molar flow rate of the mixture?

ANSWER:


Mass Fraction of A = (100 lbm/min ÷ 400 lbm/min) = 0.25
Mass Fraction of B = (300 lbm/min ÷ 400 lbm/min) = 0.75

Mole Fraction of
