Options

A. `6.023 xx10^(23)`
B. `(1)/(9.108 xx 10^(23)`
C. `(6.023 xx 10^(54))/(9.108 )`
D. `(1)/(9.108 xx 6.023 ) xx 10^8`

Answer

D

Explanation

`-= (1)/(9.108 xx 10^(-31)) ` electrons
`-= (1)/(9.108 xx 10^(-31))xx (1)/( 6.023 xx 10^(23)) ` moles of electrons
`= (1)/(9.108 xx 6.023 ) xx 10^8` moles of electrons
