$$Q = I \times t = 2 \times 3600 = 7200 C$$
$$Moles of Cu deposited = \frac{Q}{nF} = \frac{7200}{2 \times 96500} = 0.0373 mol$$
$$Mass = 0.0373 \times 63.5 = 2.37 g$$

Saved me before my mock test. Much clearer than my coaching notes.

Underrated solution. The way you set it up makes it almost obvious.

This is exactly the kind of step-by-step I needed. Respect.
