If the mass of an electron is 9*10^?28 grams. Calculate the weight of one mole of electron?

Answer:

1 mole of electrons will contain 6.023×10²³ electrons.

Let us calculate the weight of 1 mole of electrons.

1 mole of electrons weight = 9 × 10⁻²⁸ × 6.023 × 10²³

Weight of 1 mole of electrons = 54 × 10⁻⁵ gm.
