A sample of sucrose(table sugar) with a mass of 1.32g is burned in a 1L bomb calori meter. The temperature changed from 25degree celcius to 27.31 degree celcius. Calculate the heat of combustion of sucrose in units of KJ/mol. The formular of sucrose is C12H22O11

  • Chemistry -

    Note the correct spelling of celsius.

    q = mass H2O x specific heat H2O x (Tfinal-Tinitial)
    q = heat combustion
    heat combustion/g = q/1.32g\
    heat combustion/mol = (q/1.32)*molar mass. This will be in J/mol. Convert to kJ/mol.
