    combustion

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

    the experiment was heating water with a string and methanol

    the data i have is

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

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