Sea water contains $29.25\%$ NaCl and $19\%$ MgCl$_2$ by weight of solution. The normal boiling point of the sea water is _____ $^\circ$C (Nearest integer).

Assume $100\%$ ionization for both NaCl and MgCl$_2$.

Given: $K_b\left(\mathrm{H_2O}\right) = 0.52 \, \text{K kg mol}^{-1}$; molar masses of NaCl and MgCl$_2$ are $58.5$ and $95 \, \text{g mol}^{-1}$ respectively.
