Question
The number of electrons that have a total charge of 9650 coulombs is ____________.
Options
6.22 × 1023
6.022 × 1024
6.022 × 1022
6.022 × 10−34
Solution
The number of electrons that have a total charge of 9650 coulombs is 6.022 × 1022.
Explanation:
1F = 96500 C = 1 mole of e– = 6.023 × 1023 e–
∴ 9650 C = `(6.22 xx 10^23)/96500 xx 9650`
= 6.022 × 1022
