How many kilojoules are released when 90.0 methanol is burned?
I know the answer is 1020 kj but have NO idea how to get it, or what I'm doing wrong.
90 WHAT? grams, kg, moles.
Also, what do you have for the heat of combustion per mole (delta H for the reaction). If you will post that and your work I'm sure we can help with the answer. If you know the answer, post that too.
