Question

234g of benzene is mixes with 460g of toluene. Calculate the mole fraction of benzene and toluene in the solution.

Answer 1

Answer:

Mole fraction Benzene = Moles of benzene/ Moles of Solution

=$234 \div 78 \div 234 \div 78 + 460 \div 92$

=$3 \div 3 + 5$

=$3 \div 8$

Mole fraction of toluene = 1 - mole fraction of benzene = 1 - 3/8 = 5/8
