PS4 notes

There might be some confusion about the difference between partial molar properties in mixtures and intensive properties in pure components.

A partial molar something is defined by the expression given at the top problem 5, and it involves a derivative with respect to the number of molecules of a component. It is not the total quantity divided by the number of molecules in the mixture.

On the other hand, an intensive property is the quantity divided by the number of molecules, for a single component system.
