Assuming the molor mass of paraffin is 280 g/mol, calculate the # of mols of paraffin burned. Then calculate the heat of combustion of paraffin in kJ/mol
I don't think I can help you with the information provided. We need an equation (although we can wing that one) but we also need delta H for the combustion and the number of grams of paraffin burned. If this is a problem you are solving, just type the whole thing.
