3. A.) Aldrich chemical company reports the melting point of a substance to be 82.0 "C. When you measure the melting point of this pure substance, you see the substance begin to melt at 79 "Cand it finishes melting when the temperature reads 83 "C. What number(s) should you record in the notebook? B.) The melting point of an impure compound will always be (higher, lower, or the same) and occur over a (narrower, broader, or similar) temperature range when compared to its pure form.

A calibration curve constructed from absorbance values of solutions containing a known concentration of permanganate ions has the following best-fit line: y = (3.62 × 103 L/mol) x where y is the absorbance of the solution at 525 nm and x is the concentration of MnO4– (aq) in mol/L. The pathlength of the cuvettes used in the experiment is exactly 1 cm. Using this information, what is the molar absorptivity of MnO4– (aq) at 525 nm?
