The flame produced by the burner of a gas (propane) grill is a pale blue color when enough air mixes with the propane (C3H8) to burn it completely. For every gram of propane that flows through the burner, what volume (L) of air is needed to burn it completely? Assume that the temperature of the burner is 195.0°C, the pressure is 1.05 atm, and the mole fraction of O2 in air is 0.210.
