The valency of a metal 'M' is 2 and its atomic weight is 24. Calculate the molecular masses of its
sulphite

Explanation

To calculate the molecular mass of the sulphite of metal 'M', we will follow these steps:

### Step 1: Identify the valency and atomic weight of metal 'M'
- The valency of metal 'M' is given as 2.
- The atomic weight of metal 'M' is given as 24.

### Step 2: Determine the formula for the sulphite
- The sulphite ion is represented as \( \text{SO}_3^{2-} \).
