A student is given a sample of CuSO4(s) that contains a solid impurity that is soluble and colorless. the student wants to determine the amount of CuSO4 in the sample and decides to use a specterophotmeter. First, the student prepares a calibration graph by measuring the absorbances of CuSO4(aq) solutions of known concentrations. Calculate the number of miles of CuSO4 that were in the impure sample of CuSO4(s)
