Question

how many moles of electton weight one kilogrm???​

Answer 1

Answer:

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.In the SI system, the mole has about 6.023 E23 particles. This is correctly defined as a gram mole, though SI units officially designate this as a mole. Alternatively, a kg mol is equal to 1000 * g mol, and therefore can be thought of as having 6.023 E26 particles.
