The term that is used to describe the properties of solutions that are dependent on the number (not the type) of solute particles is: ?

I think you're better off using Wikipedia and the like, tbh.

That said, there are textbook references at the start of the tutorial booklets - perhaps they'd be useful?

We have never touched on anything like that before. I know it's meant to be 'independent' learning but having stuff like
