Question

Calculate the freezing point and the boiling point at 1 atmosphere of a solution containing $30g$ cane sugar (molecular mass $342$) and $150g$ water.

Given : $K_b=0.513$ and $K_f=1.86$

• A. Boiling point $=50.3$; Freezing point = $9^{o}C$
• B. Boiling point $=100.3$; Freezing point = $9^{o}C$
• C. Boiling point $=50.3$; Freezing point = $-{1.09}^{o}C$
• D. Boiling point $=100.3$; Freezing point = $-{1.09}^{o}C$

Answer 1

The correct option is D Boiling point $=100.3$; Freezing point = $-{1.09}^{o}C$
