A propane barbeque is used to heat up 400g of water in an aluminum pot until it is boiling. Using the following information, calculate the molar enthalpy of propane. You can assume the temperature of the water and the temperature of the aluminum pot are always the same.
Initial water temperature=25 degrees C
Mass of propane burned=300g
Heat capacity of aluminum=0.900j/g degrees C
Mass of aluminum pot=150g
