Practice question
Question
In 2HNO₃ + 3H₂S -> 2NO + 3S + 4H₂O, what is the mass of S produced from 63 g of HNO₃ ? (Molar masses: HNO₃ = 63, S = 32)
Explanation
Given:
In 2HNO₃ + 3H₂S -> 2NO + 3S + 4H₂O, what is the mass of S produced from 63 g of HNO₃ ? (Molar masses: HNO₃ = 63, S = 32)
Formula:
Moles of HNO₃ = 63 / 63 = 1.
Substitution & Calculation:
2 moles HNO₃ produce 3 moles S, so 1 mole produces 3/2 = 1.5 moles = 1.5 × 32 = 48 g.
Final Result:
The computed value matches expected outcome and confirms correct choice as per latest NCERT 2026-27.
