Calculate the boiling point of solution when 4g of Mg `SO_(4) (M=120g "mol"^(-1))` was dissolved in 100g of water, assuming `MgSO_(4)` undergoes complete ionization
`(K_(b) " for water " = 0.52 K " kg mol"^(-1))`

Explanation

To calculate the boiling point of the solution when 4g of MgSO₄ is dissolved in 100g of water, we can follow these steps:

### Step 1: Calculate the number of moles of MgSO₄
To find the number of moles of MgSO₄, we use the formula:

\[ \text{Number of moles} = \frac{\text{mass (g)}}{\text{molar mass (g/mol)}} \]
