Web21 jan. 2024 · Mass of an electron= 9.1 x 10^-31 Kg. Avagadro Number=6.022 x^10^23. So 1Kg of electrons contain 1.825 x10^6 moles of electrons. 1.8x10^6 moles of electrons … WebAnswer. In the one-kilogram iron weight there are 1.08·10 25 atoms, which corresponds to the chemical amount of approximately 17.9 moles of atoms. In total there are 2.8·10 26 electrons and 8.6·10 25 of them are valence. Mass of all electrons is about 0.26 g, i.e. electrons contribute very slightly to the mass of the entire weight.
WebSo approximately 1.82 × 106 moles of electrons will weigh one kilogram. Notes: The approximate mass of an electron is 9.1 × 10-31 kg. Also, it's negligible in comparison to the mass of protons or mass neutrons. Therefore the mass of electrons is not used in calculating the mass number of atoms.
