Propane, C3H8, is a hydrocarbon that is commonly used as a fuel.
Calculate the volume of air at 25°C and 1.00 atmosphere that is needed to completely combust 25.0 grams of propane. Assume that air is 21.0 percent O2 by volume. (Hint: we will see how to do this calculation in a later chapter on gases—for now use the information that 1.00 L of air at 25°C and 1.00 atm contains 0.275 g of O2 per liter.)
