Solutions

Sea water contains \(29.25 \% ~\mathrm{NaCl}\) and \(19 \% ~\mathrm{MgCl}_{2}\) by weight of solution. The normal boiling point of the sea water is _____________ \({ }^{\circ} \mathrm{C}\) (Nearest integer)

Assume \(100 \%\) ionization for both \(\mathrm{NaCl}\) and \(\mathrm{MgCl}_{2}\)

Given : \(\mathrm{K}_{\mathrm{b}}\left(\mathrm{H}_{2} \mathrm{O}\right)=0.52 \mathrm{~K} \mathrm{~kg} \mathrm{~mol}^{-1}\)

Molar mass of \(\mathrm{NaCl}\) and \(\mathrm{MgCl}_{2}\) is 58.5 and 95 \(\mathrm{g} \mathrm{~mol}^{-1}\) respectively.
