just steps is all i really need i think i need the molecular weights first then just simple molarity am i correct?

I got 0.02 g is this right?

In reality you probably could, however it is not good science as it has been considered to be contamined or already used and a new substance or solution should be obtained. I know this is wasteful but, that is just how it is.
