A solution containing both {eq}Ag^+ {/eq} and {eq}Cu^{2+} {/eq} ions is subjected to electrolysis.

a. Which metal should plate out first?

b. Plating out is finished after a current of 0.74 A is passed through the solution for 2.65 h. If the total mass of metal is 3.66 g, what is the mass percent of silver in the product?

Number of Moles:

A physical quantity that describes the material mass present in a given molar mass is known as the number of moles. The number of moles is measured in units of moles, where one mole = 6.02214078 * 10^23.
