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

Answer 1

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
