Question

the electric charge on an electron is 1.602×10^-19 how much charge is present 0.2 mole CU2 + ions​

Answer 1

Answer:

Explanation:

1.928808×10⁴ Coulomb OR 0.2 Faraday

Explanation:

Charge on 1 electron:

1.602×10^(-19) Coulomb

Charge on 1 -mole electrons:

(6.02×10²³)×(1.602×10^(-19)) Coulomb

= 96440.4 C

Charge on 1 mole Cu²+ ions:

2×96440.4 C

Charge on 0.1 mole Cu²+ ions:

0.1×2×96440.4 C

= 0.2×96440.4 C

= 19288.08 C

= 1.928808× 10⁴ C

Dividing by 96440.4

We get,

= 0.2 Faraday
