Ok I think I'm gettingvit I hope, I need to check my work.

Question

Given 0.0449 mols Pt
Find mass
0.0449 mol Pt x 195.08/1 =8.76g Pt
Am I right

Answer 1

That looks ok to me but if you put units everywhere, I would include those in the factor also; i.e.,
0.0449 mol Pt x (195.08g Pt/1 mol Pt) = xx

Answer 2

Ok thank you very much
