Answer: 
Explanation:
Elevation in boiling point is given by:

= Elevation in boiling point
i= vant hoff factor = 3 (number of ions an electrolyte produce on complete dissociation)

= freezing point constant = 
m= molality

Weight of solvent (water)= 1.000 kg
Molar mass of solute
= 142 g/mol
Mass of solute
= 175.0 g


Thus the boiling point of water when 175.0 g of
, a strong electrolyte is dissolved in 1.000 Kg of water is
