if the heat of combustion for a specific compound is -1320.0 KJ/mol and its molar mass is 67.53 g/mol how many grams of this compound must you burn to release 791.60 kj of heat

Answer 1

1320 0 kJ/mol x ?mol = 791.60 kJ.
Solve for ?mol, then
g = mol x molar mass.

Answer 2

Thank you, it worked... I was diving the wrong way
