Transcribed Image Text:You are working in the biochemistry lab and your instructor asks you to perform the following
procedure:
1. Make up 50 mL of a 0.100 M buffer solution at your assigned pH.
2. Add 9.50 mL of your buffer solution to 0.500 mL of 1.25 mM p-nitrophenol.
3. Take an absorbance spectrum from 360-500 nm using pure buffer solution as a blank or reference.
What is the final concentration of p-nitrophenol after it is diluted in the buffer solution? Express the
answer in units of mM.
Note: Only include the numerical value in your answer and use 3 significant figures. Do not include units in
your answer.
