Dr. Brown's new house will need to use propane (C3H8) gas to fuel the range, because natural gas service is not available at the location. The propane is stored as a liquid, and the gas to be burned is produced as the liquid evaporates. The propane gas consumed by a typical range burner at high power in 1 hour would occupy roughly 165 L at 25°C and 1 atm, and the range will have 6 burners. If the liquid propane were to
be stored in a tank that holds 500-gallons, how many hours would it take for the range to consume an entire tankful of propane? The density of liquid propane is 0.5077 kg/L. 1 gallon = 3.7854 L.
