Practice question

Given: How many grams of NO are produced from 63 g of HNO₃ in 3HNO₃ + P -> H₃PO₃ + 3NO ? (Molar masses: HNO₃ = 63, NO = 30) Formula: Moles of HNO₃ = 63 / 63 = 1. Substitution & Calculation: 3 moles HNO₃ produce 3 moles NO, so 1 mole produces 1 mole = 1 × 30 = 30 g. Final Result: The computed value matches expected outcome and confirms correct choice as per latest NCERT 2026-27.
