During the discharge of an alkaline battery, 4.90g of Zn..How many coulombs of electrical charge are transferred from Zn to MnO2?

During the discharge of an alkaline battery, 4.90g of Zn are consumed at the anode of the battery.

Answer 1

each zinc atom transfers two electrons
4.90 g * 1 mol Zn / 65.39 g * 2 mol e- / 1 mol Zn = 0.14987 mol e-
a mole of charge is called a Faraday
and there are 96485 C/F
0.14987 F * 96485 C/F = 1.45E4 C to 3 sig figs
