If the heat of combustion for a specific compound is -1010.0 kJ/mol and its molar mass is 46.03 g/mol, how many grams of this compound must you burn to release 388.00 kJ of heat?

  • Chemistry - ,

    1010 kJ/mol x # mols = 388 kJ
    Solve for # mols. Then mols = grams/molar mass. You know molar mass and mols; solve for grams.
