1. The problem statement, all variables and given/known data If 3.50 x 10^-3 kg of gold is deposited on the negative electrode of an electrolytic cell in a period of 2.99 h, what is the current in the cell during that period? Assume that the gold ions carry one elementary unit of positive charge. (A) 2. Relevant equations I = DeltaQ/DeltaT I = DeltaV/R (I don't think this is needed) 3. The attempt at a solution Well, I have been reading the book and asked a friend who had taken physics before but was not able to figure this out. I believe I have to use the formula I = DeltaQ/DeltaT, but not sure how I would use it as in would deltaT be 2.99 h x 60? I said that because when I used it before it was always min x 60 sec. My main problem is I never encounter where a given is in mass form with an element such as gold. How would I convert 3.50 x 10^-3 kg into a number to fit into as equation to solve for A (current). Please help me or give me some tips on where to start.
