Answer:
Explanation:
- Molality of solution(m) = 0.2 m
- Depression constant of water(
) = 1.86kg/mol
- Depression in freezing point (Δ
)
→ The equation for finding depression in freezing point is given by
Δ
→ Substituting the given datas, we get
Δ
→ The freezing point depression constant is also called Molal depression constant or cryoscopic constant
→ Depression of freezing point is directly proportional to molality of the solution.
