Molality in terms of mass

Molality in Terms of Mass

### Formula:

$$m=\frac{w\times1000}{M_m\times W}$$

### Terminologies:

- m → Molality of solution.

- w → Mass of solute in grams.

- $$M_m$$ → Molar mass of solute.

- W → Mass of solvent in grams.

- 1000 → Conversion factor.

### Usage:

- Used to calculate molality from mass data.
