What is the total charge of all the protons in 2.2 mol of he gas?

To determine the total charge of the protons in the gas, we need to know the number of protons that are present. We use Avogadro's number to know such value. We do as follows:

2.2 mol  ( 6.022x10^23 protons / 1 mol ) = 1.325x10^24 protons

Total charge = 1.6021766208×10^−19 C (1.325x10^24) = 212262.77 C

The name for subatomic particles in an atom is called a proton
