Question

The 0.1 m aqueous solutions, each of urea, common salt and sodium sulphate, are taken. The ratio of their elevation in boiling points is

Options

A.1: 1: 1
B.1: 2: 1
C.1: 2: 3
D.3: 2: 1

Solution

E­ffective molality of urea = 0.1 m

E­ffective molality of NaCl = 0.1 × 2 = 0.2 m

E­ffective molality of Na2SO4 = 0.1 × 3 = 0.3 m
