Type: MCQ-numerical-Medium-Class 12
At 100 °C, the vapour pressure of a solution of 6.5 g of a solute in 100 g water is 732 mm. If Kb = 0.52, the boiling point of this solution will be ______.
A
102 °C
B
103 °C
C
101 °C
D
100 °C
Correct Answer
Option C
Detailed Explanation
Using the formula ΔTb = i × Kb × m, where m is the molality, we calculate the boiling point elevation and find the boiling point to be 102 °C.
