Balanced equations

Question

For the balanced equation shown below, how many grams of CO would be produced by 72.0 grams of O2? C3H6+3O2 → 3CO+3H2O

Answer 1

C₃H₆ + 3O₂ → 3CO + 3H₂O ... balanced equation

molar mass O₂ = 32 g / mol

molar mass CO = 28g / mol

72.0 g O₂ x 1 mol O₂ / 32 g x 3 mol CO / 3 mol O₂ x 28 g CO / mol CO = 63.0 g CO
