Question

The partial molar volumes of the CCl4 and benzene are 122cm3/mol and 98.0 cm3/mol, respectively in a solution in which mole fraction of chloroform is 0.2. Calculate the volume occupied by 2.5 moles of the solution.

Thank yOu.

Answer 1

You have both benzene and chloroform mentioned; however, I assume you intended to write benzene for chloroform OR chloroform for benzene. I will assume the former.
nCCl4 = 0.8 x 2.5
nbenzene = 0.2 x 2.5
Then total V = (nbenzene*98 + nCCl4*122).
