In the experiment: Determining Avogadro's Number

the values that I've got are

	Trial 1	Trial 2	Trial 2
Initial mass of Copper electrode (g)	12.517	12.480	12.434
Final mass of Copper electrode (g)	12.483	12.439	12.401
Decrease in mass of copper electrode (g)	0.034	0.041	0.033
Average Current (A)	0.2901	0.3399	0.3136
Time of current application (s)	300	3000	300

1. Calculate the total charge in coulombs (C) that passed through the electrolytic cell for each 3 trials

2. Use answer from 1 to calculate the number of electrons in the electrolysis for each 3 trials. (Recall charge of an electron is 1.602x10^-19 coulombs per electron

3. Determine the number of copper atoms lost from the anode in each 3 trials. Remember that the electrolysis process uses two electrons to produce one copper ion.

4. Calculate the number of copper atoms per gram of copper lost at the anode of each 3 trials. Redution of mass from anode is same as the decrease in copper's atomic mass and produced ion's mass. (ignore mass of electron)

5. Calculate the number of atoms in 1 mol of copper for each trial.
