Question

Calculate the mole fraction of benzene in solution containing 30% by mass in carbon tetrachloride.
​

Answer 1

Answer:

Let the mass of solution be 100 gm

Mass of Benzene =30 gm

Mass of CCl

4

=70 gm

Moles of Benzene =

78

30

=0.385

Moles of CCl

4

=

154

70

=0.45 moles

Mole fraction (Benzene) =

0.385+0.45

0.385

=0.461
