Answer:
c) 0.145
Explanation:
By Raoult's Law, the pressure of a solution is equal to the molar fraction of the solvent multiplied by its vapor pressure. The solvent here is ether, so
342 = x*400
x = 342/400
x = 0.855
The solution has only ether and benzoic acid, so the molar fraction of benzoic acid will be
1 - 0.855 = 0.145
