(a) 6.023 x 1023

(b) 1/9.108 x 1031

(c) 6.023/9.108 x 1054

(d) 1/9.108 x 6.023 x 108

1/9.108 x 6.023 x 108 moles of electron weigh 1 Kg.

We know that Mass of an electron = 9.108 x 10-31 g

9.108 x 10-31 kg = 1.0 Electron

1kg = 1/9.108 x 10-31 electrons

6.023 x 1023 electrons make 1 mole, then

1/9.108 x 10-31 electrons will be = 1/9.108 x 10-31 x 1/6.023 x 1023

= 1/9.108 x 6.023 x 108 moles of Electrons

### Electrons

Subatomic particles known as electrons have an elementary charge of magnitude -1. A proton’s charge and an electron’s charge are of similar magnitude (but has an opposite sign).

Mass of electrons

The mass of an electron is 9.10938356 × 10-31 kilograms. In comparison to the mass of the proton, the mass of the electron is extremely small.

Due to their small size and mass, electrons provide for more interesting study subjects for quantum mechanics than for classical mechanics. This is due to the distinct behaviour of matter at the quantum level. Heisenberg’s uncertainty principle, for instance, states that an electron’s position and velocity are subject to significantly greater uncertainty than those of a proton or a neutron. Atomic orbitals, which are basically zones surrounding the nucleus where there is the maximum chance of finding a particular electron, are where electrons are distributed around the nuclei of atoms.

Summary:-

## How Many Moles of Electron Weigh 1 Kg?

1/9.108 x 6.023 x 108 moles of electron weigh 1 Kg. Electrons are subatomic particles which have an elementary charge of -1 magnitude.
