Solving for Avogadro's Constant?
I have electricity of 0.2 Amps going into a tin electrode. The mass of tin before running electricity if .5054 grams. The electricity runs for 5 minutes (300 seconds). The weight of tin afterwards is .4177 g.
1 Ampere = 1 coulomb per second
charge on electron = 1.602 x 10^-19 coulombs
moles = grams/molar mass
Using the above information, how can I come to the avogadro's number (close to 6.022*10^23).
The tin ion has a 2+ charge. The number of moles of tin that reacted have to be calculated.
