Answer to Question #24520 in Organic Chemistry for Bailey

Question

A brand new Battery has a mass of 249.6g. After it's been fully discharged, it's mass is still 249.6g. Explain.

Answer 1

An electron has no known components or substructure. It is generally thought to be an elementary particle. An electron has a mass that is approximately 1/1836 that of the proton and it is 9.10938291(40)×10^−31 kg. As can you see it is very and very small number in comparison to grams, that are 2.496×10^-1. It means that you can not show mass of lost electrons in grams. That's why the mass of battery is the same (in grams) before and after discharging.
