Calculate the mass per cent of different elements present in sodium sulphate (`Na_2SO_4`)

Explanation

To calculate the mass percent of different elements present in sodium sulfate (Na₂SO₄), we will follow these steps:

### Step 1: Determine the molar mass of Na₂SO₄
- Sodium (Na) has a molar mass of 23 g/mol. Since there are 2 sodium atoms in Na₂SO₄:
\[ \text{Mass of Na} = 2 \times 23 = 46 \text{ g/mol} \]
- Sulfur (S) has a molar mass of 32 g/mol:
