What is the relation between molality $(m)$ of the solution and molar mass $(M_2)$ of the solute,where $W_2$ is the mass of solute in grams and $W_1$ is the mass of solvent in grams?
- A$m = \frac{M_2 \times W_2}{1000 \times W_1}$
- B$m = \frac{1000 \times W_2}{M_2 \times W_1}$
- C$m = \frac{1000 \times W_1}{M_2 \times W_2}$
- D$m = \frac{M_2 \times W_1}{1000 \times W_2}$
