Question

If the mass of an electron is 9 into 10 to the power 28 gm weight of one mole of electron is

Answer 1

Explanation:

One mole of any gas contains 6• 023 × 10^23 atoms

or molecules.

The mass of an Electron is 9 × 10^(-)31 kg =- 9× 10^(-)28gram

So Mass of one mole gas = 9× 10^(-28) × 6× 10^ 23 grams

= 54× 10^(-5) gram.

Answer 2

1 electron has a mass of 9.1 X 10¯³¹ kg. 1 mole has 6.023 x 10²³ particles. So 1 mole of electrons has a mass of 9.1 X 10¯³¹ x 6.023 x 10²³ ≈ 5.481 X 10^(-7) kg.
