If a student received an unknown sample from the instructor and prepared a diluted solution by pipeting 15.00 ml of the sample into a volumetric flask. Subsequent to adding 2 ml of NH3 and diluting to 50.00 ml with deionizer water he read the absorbance for his diluted sample. Utilizing a previously prepared beer's curve he determined the connection of his dilution to be .00256 M. Find out the concentration of the original unknown sample?
