Unformatted text preview: of 1.602X10-19 (C/e-). We also weighed each electro prior and after the experiment to calculate the difference in mass which was then converted to moles. With moles we were able to take the number of electrons divided by two and then divide by number of moles to arrive at a value in which should be similar to Avogadro’s. Results: See Attached Pages Calculations and Graphs: See Attached Pages Discussion: When both electrodes were placed in the Sn 2+ solution prior to adding charge, it appeared that the Tin particles were beginning to bind to the Copper strip. Due to the fall off of Tin into the solution my numbers did not match up. I found through Calculation, which can be seen on following pages that the number of electrons was 8.35X10 20 . The number obtained from the Tin gained was closer to the actual value of Avogadro’s number because the amount lost is not all from electrolysis. We would not know the atomic weight because it is derived from the basics of Avogadro....
