What is the concentration of iron (II) ions in a solution if the absorbance reading from the colorimeter is 0.43 and the path length of the solution in the cuvette is 1 cm? The molar absorption coefficient of iron (II) ions is 6.16 x 10^3 M^-1 cm^-1. The solution has a volume of 10 mL. Calculate the concentration of iron (II) ions in the solution in units of Molarity.

A student needs to calculate the efficiency of an electrochemical cell that has a potential difference of 1.5 volts and a current of 0.5 amperes passing through it, with the help of Faraday's Law. If the electrode reaction produces chlorine gas with a Faraday efficiency of 79%, and the overall voltage efficiency of the cell is 85%, what is the efficiency of the electrochemical cell?

A student conducted an experiment to calculate the Faraday constant using a silver-copper voltaic cell. The masses of the copper and silver electrodes were 4.023g and 4.721g respectively. The cell was run for 782 seconds at a constant current of 0.250A. Calculate the value of the Faraday constant for this experiment.
