2. The optical density of a standard solution of iron converted into a colored compound is 0.64. The concentration of this solution is 2.3×10-5 mol/l. The optical density of a solution containing 4.6×10-5 mol/l is 1.34. Calculate the value of the molar absorption coefficient of this solution if the thickness of the absorbing layer is 1 cm.
