Answer:
<h2>7142.86 moles</h2>

L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
We have the final answer as
<h3>7142.86 moles</h3>
Hope this helps you
Electrode potential is concentration dependent as it is composed of two half-cells with same electrodes but different concentrations. One acting to dilute a more concentrated solution, while the other concentrates a more diluted solution — which then creates a voltage that is in equilibrium. This why we need both positive and negative sides of a battery as a power source and make something work.
