If the heat of combustion for a specific compound is -1310.0 kJ/mol and its molar mass is 75.45 g/mol, how many grams of this compound must you burn to release 708.60 kJ of heat?

Answer 1

1310 kJ/mol x ?mol = 708.60 kJ.
Solve for ?mol.

Then mol = grams/molar mass. You know mol and molar mass, solve for grams.
