If `0.04 M Na_(2)SO_(4)` solutions at `300K` is found to be isotonic with `0.05M NaCl` (`100%` dissociation) solutions. Calculate degree of dissociation of sodium sulphate.

Explanation

To solve the problem of calculating the degree of dissociation of sodium sulfate (Na₂SO₄) when it is isotonic with sodium chloride (NaCl), we can follow these steps:

### Step 1: Understand Isotonic Solutions
Isotonic solutions have the same osmotic pressure. The formula for osmotic pressure (π) is given by:
\[ \pi = i \cdot C \cdot R \cdot T \]
where:
