Answer:
Boiling T° for solution is 100.2°C
Freezing T° for solution is - 0.95°C
Explanation:
Formula for boiling point elevation:
Boiling T° for solution - Boiling T° for pure solvent = Kb . m
Formula for freezing point depression:
Freezing T° for pure solvent - Freezing T° for solution = Kf . m
Boiling T° for pure solvent = 100°C
Freezing T° for pure solvent = 0°C
Kb = Ebulloscopic constant for water → 0.512°C /m
Kf = Cryoscopic constant for water → 1.86°C / m
Let's replace data:
Boiling T° for solution = 0.512°C/m . 0.516 m + 100°C = 100.2°C
Freezing T° for solution = 1.86°C/m . 0.516 m - 0°C = - 0.95°C
