NEET Chemistry Concentration Terms MCQ Question
Type: MCQ-numerical-Medium-Class 12
A solution is prepared by dissolving 50 g of glucose (C6H12O6) in 450 g of water. Calculate the mass by volume percentage (w/v) of glucose in the solution, given that the density of the solution is 1.1 g/mL.
A
9.09%
B
11.11%
C
10.00%
D
12.50%
Correct Answer
Option A
Detailed Explanation
The mass by volume percentage (w/v) is calculated using the formula: (mass of solute / volume of solution) × 100. Here, the volume of solution can be calculated from the mass and density: 500 g / 1.1 g/mL = 454.55 mL. Therefore, the w/v percentage is (50 g / 454.55 mL) × 100 = 9.09%.
