Calculate the mass of silver deposited at cathode when a current of $2\text{ amperes}$ is passed through a solution of $\text{AgNO}_3$ for $15\text{ minutes}$. (at. wt. of $\text{Ag} = 108, 1\text{ F} = 96,500\text{ C}$)

Calculate the emf and $\Delta G$ for the cell reaction at $298\text{ K}$: $\text{Mg}(s) \mid \text{Mg}^{2+}(0\cdot1\text{M}) \parallel \text{Cu}^{2+}(0\cdot01\text{M}) \mid \text{Cu}(s)$ Given $E^\circ_\text{cell} = 2\cdot71\text{ V}$, $1\text{F} = 96,500\text{ C}$
