How many moles of electrons weigh one kilogram?

A

`6.023 xx 10^23`

B

`(1)/(9.108) xx 10^31`

C

`(6.023)/(9.108) xx 10^54`

D

`(1)/(9.108 xx 6.023 ) xx 10^6`

Text Solution

Verified by Experts

The correct Answer is:
D
1 mol of electrons weight ` = 9.108 xx 10^(-31) xx 6.022 xx 10^23 kg `
or 1kg of electrons `= (1)/(9.108 xx 6.022) xx 10^8` or `0.0182 xx 10^(8)` mol
