charge of two kilogram electrons is
Answers
2.3 kg electrons x 1 electron/9.11x01-31 kg = 2.52x1030 electrons
1.602x10-19 C/electron x 2.52x1030 electrons = 4.04x1011 Coulombs = total charge of 2.3 kg of electrons.
The mass of a proton is significantly larger than that of an electron. It is 1.672x1o-27 kg/proton. Thus...
2.3 kg protons x 1 proton/1. 672x10-27 kg = 1.38x1027 protons
1.38x1027 protons x 1.602×10-19 C/proton = 2.21x108 coulombs = charge of 2.3 kg of electrons
Please note the difference in mass between an electron and a proton. Electrons have essentially no mass relative to a proton and a neutron.
1 kg
What is the total charge on 1 kg of electrons?
One has to find number of electrons (dividing 1kgover mass of an electron =9.1*10^-31 kg) and multiply it by an elementary charge e = 1.6*10^-19 C.
