STANDARD Chemistry Molality MCQ Question

Type: MCQ-numerical-Medium-Class 12

What will be the molality of a solution of glucose in water which is 10% w/W?

A

0.01 m

B

0.617 m

C

0.668 m

D

1.623 m

Correct Answer

Option B

Detailed Explanation

10 g of glucose is present in 100 g of solution. Mass of H₂O = 100 - 10 = 90 g. Molality = (10/180) × (1000/90) = 0.617 m.
