# Chemistry a level - enthalpy stuff

This discussion is closed.

I've just finished doing an experiment on Enthalpy change of combustion of propan-1-ol and some other alcohols, and i have worked out the enthalpy change of combustion for propan-1-ol but i don't know how to calculate the Quantity of energy,Q, released by propan-1-ol when it burned. I'll be grateful of any help.

Q = mass of water x specific heat capacity of water x temperature change
