1. ## 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
