Describe an alternate method for determining the molar concentration of your unknown sample of copper (ii) sulfate solution, using the standard data

Being that the number of moles of the unknown sample and any of the standard solutions is equal, the formula M1V1 = M2V2 could work. As the volumes of each are given as well as one of the molarities, the other molarities could be calculated. Another way would be to use the Beer-Lambert law, the equation is, A=εlc εl = A/c Since A is absorbance (the y-axis) and c is the concentration (the x-axis) on the graph, y/x is rise over run, which is the slope. Since the slope and the absorbance of the unknown are known, the concentration can be calculated. C = A/εl
