A 56.0 g ball of copper has a net charge of 2.10 μC. What fraction of the copper’s electrons has been removed? (Each copper atom has 29 protons, and copper has an atomic mass of 63.5.)
Answers: 3
.
and a charge of 
. Based on the Principle of Charge Conservation, 
in electrons must be removed in order to create a positive net charge. The amount of removed electrons is found after dividing remove charge by the charge of a electron:
- Mass of the ball, measured in kilograms.
- Atomic mass of cooper, measured in grams per mole.
- Avogradro's Number, measured in atoms per mole.
, 
and 
, the number of atoms is:
