I did a GCSE exam for that last year, but now I can't remember :(

But if u need the Mr of Ar u can use a periodic tafel, tabel to work it out.

Practically all I can remember is the equation mass = Mr x moles, but then u probably already knew that :S

I already know that and I have solved it with the Mr, I want to know if there is any way to solve it without it, since out of the 10 problems it is the only one that the Ar is not gegeven so I assume I don't have to use it
