Assume that the mass of the Cu electrode changes by "x" grams in a certain period of time. Write a mathematical expression for the change in mass of the Zn electrode during the same time. Given information:
Cu^2+ +Zn ---> Cu+Zn^2+ (net-ionic equation for the reaction in the cell)
Ecell is 1.10 V

Please tell me if there is any other information you need to solve the problem.
