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

But if tu need the Mr o Ar tu can use a periodic mesa, tabla to work it out.

Practically all I can remember is the equation mass = Mr x moles, but then tu 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 dado so I assume I don't have to use it
