Question

What volume of H₂ gas at 27 ° C and 1.0 atm will be produced from the reaction oF₄.0 g of Na with H₂O? 2 Na + 2 H₂O→H₂ + 2 NaOH

Quizplus · Accepted Answer

First, calculate moles of Na: 4.0 g / 23.0 g/mol = 0.174 mol. From the balanced equation, 2 moles of Na produce 1 mole of H2, so 0.174 mol Na produces 0.087 mol H2. Using the ideal gas law at 27°C (300 K) and 1 atm, V = nRT/P = (0.087 mol)(0.0821 L·atm/mol·K)(300 K) / 1 atm = 2.1 L.
