It is found that elevation in boiling point of a given aq. `NaCl` solution is equal to depression in freezing point of `0.25` molal aq. `Na_(2)CO_(3)` solution. If `K_(f)=1.86^(@) "mol"^(-1) kg`, calculate molality of `NaCl` solution, assume complete ionisation of `NaCl` and `Na_(2)CO_(3)` in aqueous solution.
