Practice question

Given: What is the molality of a solution containing 10 g of sugar (molar mass = 342 g/mol) dissolved in 500 g of water? These values define the system as per NCERT data. Formula: Moles = 10 / 342 ≈ 0.0292 mol. This is standard NCERT relation. Substitution & Calculation: Molality = 0.0292 / 0.5 ≈ 0.0584 m. Result: The computed value matches expected outcome and confirms correct choice as per NCERT.
