Question

How many moles of electron weight 25 kg? ​

Answer 1

Explanation:

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.

Answer 2

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.

1.8x10^6 moles of electrons weigh 1 kg

1.8x10^6x25 moles of electrons wei gh 25 kg = 4.5x10^7
