7. Calculate the number of grams water produced by the complete reaction of 14.5 g of oxygen (theoretical yield). 2H2 + O2 2H2O → 14.5 g O2 x 1 mole x 2 mole H2O x 18.02 g = 16.3 g H2O 32.0 g 1 mole O2 1 mole 8. Calculate the mass of carbon required to produce 5.67 g of iron. 2Fe2O3 + 3C 4Fe +3CO2 → 5.67 g Fe x 1 mole x 3 mole C x 12.0 g = 0.915 g C 55.8 g 4 mole Fe 1 mole 9. Calculate the amount of oxygen in grams produced by the reaction of 125 g of water. 2H2O 2H2 + O2 → 125 g H2O x 1 mole x 1 moleO2 x 32.0 g = 111 g O2 18.02 g 2 mole H2O 1 mole 10. Calculate the theoretical yield in grams of CO2 produced by the reaction of 15.6 g of iron III oxide. 2Fe2O3 + 3C 4Fe +3CO2 → 15.6 g Fe2O3 x 1 mole x 3 mole CO2 x 44.0 g = 6.45 g CO2 159.6 g 2 mole Fe2O3 1 mole 11. Calculate the number of molecules of CO2 produced by the reaction of 2.45g of iron III oxide.
