An industrial waste water I found to contain 8.2% `Na_(3)PO_(4)` and 12% `MgSO_(4)` by mass in solution. If % ionisation of `Na_(3)PO_(4) "and"MgSO_(4)`Are 50 and 60 respectively then its normal boiliung point is [`K_(b)(H_(2)O) = 0.50 K kg "mol"^(-1)`] :
A. `102.3^(@)C`
B. `103.35^(@)C`
C. `101.785^(@)`
D. none of these
