1 pts Calculate the concentration of the unknown VOA sample, given the following experiment. Step 1: A 2.00 mL aliquot of an unknown VOA sample was diluted to 100.0 mL and the absorbance measured to be 0.326. Step 2: A 2.00 mL aliquot of an unknown VO4 sample was placed in a 100.0 ml flask. A 2.00 mL aliquot of a 100.00 ppm V04- standard was added to the flask and the absorbance measured to be 0.669. Report your answer to 4 significant figures. No marks for units. 1 pts Calculate the concentration of the unknown VOA sample, given the following experiment.
