If the heat of combustion for a specific compound is -1080.0 kJ/mol and its molar mass is 58.29 g/mol, how many grams of this compound must you burn to release 300.60kJ of heat?

  • Chemistry -

    1080 kJ/mol x # mols = 300.6 kJ
    Solve for # mols, then n = grams/molar mass. You know molar mass and n, solve for grams.
