Propane gas (C3H8) reacts with oxygen gas (O2) to cook some hamburgers. This is a combustion reaction, so the products are carbon dioxide gas (CO2) and water vapor (H2O). Use the balanced equation: C3H8 + 502 > 3CO2 + 4H2O

10. How many grams of C3H8 would you need to react to make the 10 grams of water from problem 10? Show your work.
