Question

Calculate the number of moles present in 1 kg of electrons.

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. 1.8x10^6 moles of electrons weigh 1 kg.

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 weight 1 kg
