Assuming the quantity of current passing through the zinc and copper electrolytes is the same, mass of Zinc deposited is (x/64) × 65.0 g.
Electrolysis is the decomposition of a substance known as an electrolyte when electric current is passed through its solution or molten form.
The mass of an electrolyte deposited when current is passed is dependent on the current and the charge on the ion.
In the electrolysis of copper and zinc, assuming the quantity of current passed through their solution are the same, the moles of each zinc and copper deposited will be the same since the charges on their ions are the same.
Assuming x g of copper is deposited.
molar mass of copper = 64.0 g
molar mass of Zinc = 65.0 g
moles of copper deposited = x/64
moles of zinc deposited = x/64
mass of Zinc deposited = (x/64) × 65.0 g
Therefore, the mass of Zinc deposited is (x/64) × 65.0 g.
