Coefficients in a balanced reaction give relative amounts in moles. The ratio assumes the stated reactant is limiting, the other is sufficient and conversion is complete. A mole ratio is not automatically a gram ratio. Paper chemistry only.

Worked example

For N2 + 3 H2 -> 2 NH3, 3 mol H2 can yield 2 mol NH3 with sufficient N2 and complete conversion.

Question 1 Paper reaction N2 + 3 H2 -> 2 NH3: 18 mol H2 is limiting, N2 is sufficient, and conversion is complete. What amount of NH3 forms in mol? Answer

Question 2 Paper reaction N2 + 3 H2 -> 2 NH3: 21 mol H2 is limiting, N2 is sufficient, and conversion is complete. What amount of NH3 forms in mol? Answer

Question 3 Paper reaction N2 + 3 H2 -> 2 NH3: 24 mol H2 is limiting, N2 is sufficient, and conversion is complete. What amount of NH3 forms in mol? Answer

Question 4 Paper reaction N2 + 3 H2 -> 2 NH3: 27 mol H2 is limiting, N2 is sufficient, and conversion is complete. What amount of NH3 forms in mol? Answer

Question 5 Paper reaction N2 + 3 H2 -> 2 NH3: 30 mol H2 is limiting, N2 is sufficient, and conversion is complete. What amount of NH3 forms in mol? Answer
