The mass of one mole of electron is

A

`9.1 xx 10^(-28) g`

B

`0.55 mg`

C

`9.1 xx 10^(-24)g`

D

`1.008 mg`

Text Solution

Verified by Experts

The correct Answer is:
B
Mass of an electron `= 9.1 xx 10^(-28) g`
`:.` mass of one mole
`= 9.1 xx 10^(-28) xx 6.02 xx 10^(23)`
`= 54.78 xx 10^(-5) g = 0.55 mg`.
