To calculate the concentration of a solution using Beer's Law, you can use the formula A lc, where A is the absorbance of the solution, is the molar absorptivity of the substance, l is the path length of the cuvette, and c is the concentration of the solution. By rearranging the formula, you can solve for the concentration of the solution, c A / (l).
