an ampere is a Coulomb per second
there are 6.242E18 electrons in a Coulomb
moles of electrons = (6.242E18 * 3.25 * 500 * 60) / 6.02E23
it takes two electrons to generate a Cl2 molecule
find the moles of electrons
... divide by two to find the moles of Cl2
multiply by the molar mass of Cl2 to find the grams
In the electrolysis of aqueous NaCl, how many grams of Cl2 are generated by a current of 3.25 amperes flowing for 500 minutes?
