@zzz0mg Simple, just take what you ended up with (3.75kJ enthalpy change) and divide it by the number of moles of substance. Remember, you got the mols of substance from the mass of the sample (4.24g LiCl in this case), which equates to .100 moles LiCl. Again, take the energy change which you calculated before anything else(3.75Kj), and divide it by the moles of substance (.100) to get 37.5kJ/1mol LiCl.
How would you calculate it if the question said "per ONE mole" ? thanks for uploading! (:

Good video, but the quality of the microphone is awful.

I've got my mic issues fixed now and have been re-doing some of the bad ones. This one is definitely on the list!
