3.9 Stoichiometric Calculations: Amounts of Reactants and Products This section will be explained by solving the following problem. C3H2(g) 1 mole + 502(g) > 3CO2(g) + 5 moles 3 moles (Always work with moles and not grams) 4H2O(g) 4 moles 1. What mass of oxygen will react with 96.1 g of propane C3H2 ? Moles of propane = 96.1 g/44.1 g = 2.18 moles Moles of oxygen = 2.18 moles C3H, x 5 moles 0/1 moles CzHg = 10.9 moles Mass of oxygen = 10.9 moles x 32g/1 mole O2 = 349 g 8 = = 2. What mass of carbon dioxide is produced when 96.1g of propane is combusted with oxygen? Moles of CO2 = 2.18 moles C2H, x 3 moles CO2/1 moles C3H, = 6.54 moles Mass of CO2 = 6.54 moles x 44g/1 moles CO2 = 288g
