The problem can be stated as follows: A mixture of three solvents, A, B, and C, is provided. The composition of the mixture is unknown but it is suspected that solvent C is present only in small quantities. Using gas chromatography, how can you determine the relative amounts of each solvent in the mixture and confirm the presence of solvent C in the mixture?

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?
