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.
