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

But if Du need the Mr oder Ar Du can use a periodic tabelle to work it out.

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