Question: A student wants to quantify the amount of iron (Fe) in a water sample using coulometry. The sample has a mass of 50.0 g and contains iron in the form of Fe(II) ions. The student sets up the electrochemical cell and begins the oxidation reaction, which requires a current of 16.0 A for 1200 s. What is the concentration of Fe(II) ions in the water sample in mol/L?
