Mole Ratio from Electrolytic Deposition
During the electrolysis of a solution containing a mixture of Cu²⁺ and Ag⁺ ions, a current of 2.50 A is applied for 30.0 minutes. As a result, 1.97 g of Cu and 4.06 g of Ag are deposited. What is the mole ratio of Cu²⁺ to Ag⁺ in the original solution?
A
3:1
B
0.82:1
C
1:1
D
