Type: MCQ-numerical-Medium-Class 12

What weight of glycerol should be added to 600 g of water in order to lower its freezing point by 10°C? (Kf = 1.86°C m⁻¹)

A

496 g

B

297 g

C

310 g

D

426 g

Correct Answer

Option B

Detailed Explanation

Using the formula ΔTf = Kf × m = (Kf × W₂ × 1000) / (M₁ × W₁), we find W₂ = (10 × 92 × 600) / (1.86 × 1000) = 296.77 g, which is approximately 297 g.
