Question

Which of the following ratio is irrelevant formula mass and experimental molecular weight obtained from colligative properties of solution of ionic solid of AB type ?

(a)   3 : 2

(b)   5 : 3

(c)   4 : 3

(d)  5 : 2 

Answer 1

Correct option  (d) 5 : 2 

Explanation :

where M = Actual molecular mass of solute

Mob = experimental molecular mass of solute.

For AB Type ionic compound i ≤ 2
