You need to know the molar mass of the substance in question.For methanol it's 32.0420 g/mol For ethanol it's 46.0687 g/molFor propanol it's 60.0953 g/molFor butanol it's 74.1220 g/molStarting with the heat of combustion in J/g, here's what you do.X J/g x (1 kJ / 1000 J) x (molar mass / 1 mol) Be sure to multiply and divide as indicated, or you won't get the correct result.I hope that helps. Good luck!... Show More
