Enthalpy values for water
WebFirst determine the moles of methane: 4.5 g x 1 mole/16 g methane = 0.28125 mol CH4. Then multiply the amount of moles by the known per mole amount of Enthalpy shown: 0.28125 * -802 kJ = -225.56 kJ or -2.3e2 kJ. You may note that the units on the Enthalpy value are only shown as kJ and not kJ/mol in the reaction.
