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
spectrophotometer. First, the student prepares a calibration graph
by measuring the absorbances of CuSO4(aq) solutions of known
concentrations. The graph is shown below.a) (a) The student dissolves the entire
impure sample of CuSO4(s)CuSO4(s) in enough distilled water to make
100.mL100.mL of solution. Then the student...
