Mixture of A,B,C if the mole fraction of A is 30 and B is 35 Volume percent calculate the mass and mole fraction of each compnant. given that A is methane, B is ethane, C is propane. use SI unit and English unit.

Answer 1

Xa = 0.30
Xb = 0.35
Xc = 1.0-0.3-0.35 = 0.35

Then Xa = 0.30*molar mass CH4
Xb = 0.35*molar mass ethane
Xc = 0.35* molar mass propane.

Answer 2

I just mislabeled the final results.
grams = 0.30*molar mass CH4.
grams = 0.35*molar mass ethane
grams = 0.35*molar mass propane.
