Quizplus · Accepted Answer

The balanced equation is C3H8 + 5O2 → 3CO2 + 4H2O. The molar mass of CO2 is 44.01 g/mol, so 7.26 g CO2 is 0.165 mol. From the stoichiometry, 1 mol of C3H8 produces 3 mol of CO2, so 0.165 mol CO2 comes from 0.055 mol C3H8. The molar mass of C3H8 is 44.1 g/mol, so 0.055 mol is 2.42 g.
