How is the amount of current flowing through an electrolytic cell related to the amount of product produced in the redox reaction? Match the items in the left column to the appropriate blanks in the sentences on the right. multiplied coulombs Avogadro's 1 mol Faraday's 1g ampers 6.022 x 10¹ mol volts divided The number of moles of electrons that have flowed in a given electrolysis cell can be determined by measuring the total charge that has flowed through the cell. If the amount of current flowing through the cell is by the time that the current flowed, the total charge that passed through the cell in that time can be found. The relationship between charge and the number of moles of electrons constant, which corresponds to the charge in is given by of of electrons. These relationships are used to solve problems involving the stoichiometry of electrolytic cells. Reset Help
