Chem help finding grams of compound required to release heat

If the heat of combustion for a specific compound is -1070.0 kJ/mol and its molar mass is 68.95 g/mol, how many grams of this compound must you burn to release 627.70 kJ of heat?

Thank you so much!

627.7 kJ / 1070 kJ/mol = 0.5866 moles

0.5866 mol X 68.95 g/mol = 40.45 grams
