WebSolve the equation to find the concentration of our unknown solution: 0.3417 mol L-1 = [CuSO 4(aq)] However, we are only justified in using 2 significant figures to express the concentration of our unknown solution, that is: [CuSO 4(aq)] = 0.34 mol L-1. In summary, to determine the concentration of a coloured solution using colorimetry: WebOne of the most fundamental methods used to calculate the concentration of an unknown liquid is the use of a calibration curve. A calibration curve is basically a graph that …
