In this lesson, we will learn how to calculate the molar mass of a material from the electroplating current and rate of deposition.
Q1:
After the electrolysis of an aqueous solution of copper(II) sulfate, a deposit of 0.50 g of copper is left on the cathode.
How many moles of electrons are required to generate this deposit of copper?
Taking the charge of an electron to be 1.6×10 C, what is the total charge required to produce this deposit?
