QUESTION 7
0.25mL of a stock solution of ortho-nitrophenol (ONP) is diluted to a final volume of 3mL in a cuvette. You measure the absorbance at 410nm of the ONP in the cuvette.
This gives a reading of 0.723 absorbance units
Given that the molar absorption coefficient, e, for ONP is 3.47 x 103 M-1 cm-1 and the path length is 1cm, what is the concentration of the ONP in the stock solution?
