# Converting kJmol^-1 to kJkgmol^-1 Watch

1. EDIT: Sorry, title is wrong.

So this is what I did to try and work this out, say for an enthalpy change of +29.3:

Say the molecular mass is 119.5.

As this is how to convert the units, surely you would apply this to the enthalpy change?

This clearly isn't correct, what have I done wrong?

You multiply by the number of moles in a kilogram ...
3. That makes sense, K=kj/mol x mol/kg = kj/kg, but why doesn't my method work?
