Calculate the mole fraction of the solution made by mixing 1.998 g of p-xylene (C8H10) and 130 g of cyclohexane (C6H12).

Mole fraction of p-xylene?
Mole fraction of cyclohexane?

Answer:
Moles of p-xylene 1.998/106

Moles of C6H12 = 130/84

Mole fraction of C6H12 = 0.988

Mole fraction of p-xylene = 0.012
