Question

2 g of solute is dissolved in two different solvent A and B having 200 g mass each. Given that K_b(A) : K_b(B) = 1 : 2. Calculate the ratio of ΔT_b(A): ΔT_b(B). 

(a) 1:2 

(b) 2:3 

(c) 3:1

(d) 3:4

Answer 1

Correct option is (a) 1:2 

Mass of solute = 2g 

Mass of solvent A = 200 g 

Mass of solvent B = 200 g 

K_b(A): K_b(B) = 1 : 2 (given)
