6.70 moles of C3H8?
2. When 2.0L of propane gas (C3H8) is combusted to form water vapor and carbon dioxide at a temperature of 250C and a pressure of .850 atm, what mass of water vapor will result?
Hint: use ideal gas law to find moles of propane gas; then do a mole to gram stoichiometry problem from propane to water
Answers: L; 11.2 L; 150. L g water vapor
