Question

If the mass of an electron is 9×10^-28 grams,weight of one mole of electron is

Answer 1

Bonjour!

1 mole = 6.022 × 10²³ electrons.

Given mass of electron = 9 × 10^-28 grams

Mass of 1 mole electron = 6.022 × 10²³ × 9 × 10^-28

= 54.198 × 10^-5 grams

Hope this helps...:)

Answer 2

Answer: The mass of 1 mole of electron is equal to $54.198\times 10^{-5}g$

Explanation:

According to mole concept:

$6.022\times 10^{23}$ number of electrons are contained in 1 mole of an element.

We are given:

Mass of 1 electron = $9\times 10^{-28}$

Mass of 1 mole of electron will be equal to = $9\times 10^{-28}g\times 6.022\times 10^{23}=54.198\times 10^{-5}g$

Hence, the mass of 1 mole of electron is equal to $54.198\times 10^{-5}g$
