My chemistry homework question is:
The combustion of 0.500 g of propane (C3H8) causes a variation of 10.0°C in a calorimeter whose heat capacity is 2.312 kJ/°C. What is the molar heat of combustion of propane?

Hi ZenShark5377,
To find the molar heat of combustion, you'll need this formula:

In your homework you're looking for the molar heat instead, you'll need to switch the mass in the formula for a quantity in mol. You can transform the mass of propane in mol and then use the formula with the other information in your homework.
Here's a concept sheet on this subject:
I hope that helps and feel free to write to us again!
