What mass of water is produced when 10.0 L of oxygen react completely in the following equation? 2 C₂H₆(g)+ 7 O₂(g)$\rarr$ 4 CO₂(g)+ 6 H₂O(g)

Question

Quizplus · Accepted Answer

10.0 L of oxygen is 10.0 L * (1 mol/22.4 L) = 0.446 mol of oxygen.According to the balanced equation, 7 moles of oxygen react to produce 6 moles of water.Therefore, 0.446 mol of oxygen will react to produce 0.446 mol * (6 mol H2O / 7 mol O2) = 0.312 mol of water.The mass of 0.312 mol of water is 0.312 mol * (18.0 g/mol) = 5.62 g.Therefore, the correct answer is A) 6.90 g.
