what mass of CO2 can be produced?

Question

Given the equation below, 13.58 grams of Fe₂O₃, and excess CO, what mass of CO₂ can be produced? Please round the answer to two digits after the decimal point.

Fe₂O₃ + 3 CO = 2 Fe + 3 CO₂

Answer 1

Fe₂O₃ + 3 CO => 2 Fe + 3 CO₂ .. balanced equation

moles Fe₂O₃ present = 14.58 g Fe₂O₃ x 1 mol Fe₂O₃ / 159.69 g = 0.09130 mols

mass of CO₂ produced = 0.09130 mol Fe₂O₃ x 3 mol CO₂ / mol Fe₂O₃ x 44.01 g CO₂ / mol = 12.05 g CO₂
