    combustion

    I need to know how to calculate  \delta{H}_{comb} for CH3OH(methanol)

    the experiment was heating water with a string and methanol

    the data i have is

    t_{1}=30^o C
    t_{2}=65^o C
    temp change= 35^o C
    mass of water 100.0 g
    mass of methanol  50.0 g
    mass after water heater methanol 44.0 g

    how do i calculate \delta{H}_{comb} of methanol
