Posted by Anonymous on Tuesday, June 19, 2012 at 5:28pm.

Methanol(MM=32.04g/mole) is sometimes used as fuel for race cars, since methanol fires are easily extinguished with water. the energy content o methanol is investigated in a high-quality calorimeter for which the heat capacity is known to be 4.5Kj/C. When 17.62g of liquid of methanol is burned in the calorimeter. its temperature rises from 21 to 99.03celicus. Find the enthalpy for the combustion of methanol.

I used the equation q = ms(Tfinal - Tinitial) and i got an answer of 5394.09kJ. Did i do it correctly?
