Question

the number of moles of electrons which weigh 1 kg is ​

Answer 1

Answer:

Mass of an electron= 9.1 x 10^-31 Kg. Avagadro Number=6.022 x^10^23. =1.825 x 10^6 moles of electrons. So 1Kg of electrons contain 1.825 x10^6 moles of electrons

Answer 2

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 weigh 1 kg.
