An aerosol spray can with a volume of 456 mL contains 3.09 g of propane gas (C3H8) as a propellant. If the can is at 23°C, what is the pressure in the can? What volume would the propane occupy at STP?
The can says that exposure to temperatures above 130°F may cause the can to burst. What is the pressure in the can at this temperature?
