# Problem: Magnesium is obtained by electrolysis of molten MgCl2.Several cells are connected in parallel by very large copper buses that convey current to the cells. Assuming that the cells are 96 % efficient in producing the desired products in electrolysis, what mass of Mg is formed by passing a current of 9.5×104 A for a period of 26 hr?

We have to determine what mass of magnesium is formed by electrolysis when a current of 9.5×104 A for a period of 26 hours.

We will follow these steps to solve this problem:

Step 1: Write an equation for the reduction of MgCl2 to Mg metal.

Step 2: Determine the current passed through the cells at 96 % efficiency.

Step 3: Determine the amount of electric charge passed through the cells.

Step 4: Calculate the amount of Mg metal formed. ###### Problem Details
