The molecular formula of ammonium sulphate is ______. `[NH_4SO_4 // (NH_4)_2SO_4]`

Explanation

To find the molecular formula of ammonium sulfate, we can follow these steps:

### Step 1: Identify the ions involved
- Ammonium ion (NH₄⁺) has a charge of +1.
- Sulfate ion (SO₄²⁻) has a charge of -2.

### Step 2: Determine the ratio of ions
To balance the charges, we need to combine the ammonium and sulfate ions in such a way that the total positive charge equals the total negative charge.
