How do you Convert 40.79 kilojoules per mole to joules per grams?

Answer 1

40.79 H2O kj/moles x 1 moles/18 grams= 2.266/1000=0.002266 joules/grams

Answer 2

To convert from kilojoules per mole to joules per gram, you need the molar mass of the substance. Once you have the molar mass, you can convert as follows: 1 kJ/mol = 1000 J/mol 40.79 kJ/mol = 40.79 * 1000 J/mol = 40790 J/mol

Then, divide by the molar mass in grams/mol to get joules per gram.
