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

Explanation

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

### Step 1: Determine the formula of the chlorate compound
Given that the valency of metal 'M' is 2, it will form a positive ion with a charge of +2. The chlorate ion (ClO3) has a charge of -1.

To balance the charges, we can use the crisscross method:
- The charge of metal 'M' is +2.
- The charge of the chlorate ion is -1.
