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
HOPE IT HELPS YOU

wrong
why borz
answer is
10^8/9.1×6.022
its absolutely correct....
this is answer
9.1101* 10^-31 kg contains 1 electron .
therefore, 1 kg will contain 1/(9.1101 * 10 ^ -31 electrons)
which is equal to 1/(9,1101 * 10 ^ -31)(6.022 * 10 ^ 23) MOLES OF ELECTORN
WHICH IS EQUAL TO 10^8/(9.011*6.022) MOLES
therefore, 1 kg will contain 1/(9.1101 * 10 ^ -31 electrons)
which is equal to 1/(9,1101 * 10 ^ -31)(6.022 * 10 ^ 23) MOLES OF ELECTORN
WHICH IS EQUAL TO 10^8/(9.011*6.022) MOLES

mass of an electron= 9.1× 10^-31. one mole of electron= 6.023× 10^23 . mass of one mole electron= 6.022× 10^23 × 9.1 × 10^-31 . number number of moles of electron= 1kg = 10^8/ 9.1 × 6.023 = 1.825 × 106 moles of electron. I hope my answer help you ✌️✌️
