Well you didn't really provide a lot of details here but I would assume you are saying 4.86 atoms times 1021, that is how it is written. Or are you saying 4.86 to the 1021st power? I'll go with the first one and hope that is what your question is about. Platinum has an atomic weight of 195.084 and that equates to .4 pounds per mole, the way I read it. This would be 4.86x.4=1.944 so that 1.944x1021=1984.824. So you use the atomic chart to find the molecular weight and then calculate from there. Got it?
