Calculate the mass of Na₂O that can be produced by the reaction of 4.00 g of sodium and 2.00 g of oxygen in the reaction 4 Na + O₂ $\rightarrow$2 Na₂O.

Question

Quizplus · Accepted Answer

The limiting reactant is sodium (Na). The molar mass of Na is 23 g/mol, so 4.00 g of Na is 0.174 mol. The balanced equation shows 4 mol of Na reacts with 1 mol of O2 to produce 2 mol of Na2O. Therefore, 0.174 mol of Na produces 0.087 mol of Na2O. The molar mass of Na2O is 62 g/mol, so 0.087 mol of Na2O is 5.39 g.
