Practice question

Given: What is the mass percentage of a solution made by dissolving 30 g of sucrose in 120 g of water? Formula: Total mass of solution = 30 g + 120 g = 150 g. Substitution & Calculation: Mass % = fracMass of sucroseTotal mass × 100 = 30/150 × 100 = 20% . Final Result: The computed value matches expected outcome and confirms correct choice as per latest NCERT 2026-27.
