Question

The correct expression relating molality (m), molarity (M), density of solution (d) and molar mass (M2) of solute is :

Options

A.m = × 1000   
B.m = × 1000   
C.m = × 1000   
D.m = × 1000   

Solution

Molarity = M
Let volume of be 1 ltr.
∴ mass of solvent = 1000 d - M × M2
Molality = m = × 1000
