A 0.1375-g sample of magnesium is burned in a constant volume calorimeter tha has a heat capacity of 3024 J/C. the temperature increases by 1.126 C. calculate the heat given off by the burning Mg in kJ/g and kJ/mol

  • chemistry -

    q = 3024 x delta T.
    kJ/g = 1000*q/0.1375
    kJ/g x (24.32 g Mg/mol Mg) = kJ/mol.
