    3) Solution 1 contains a ratio of 2.54 :1 pentanol to hexanol. When the chromatogram was run, the peak area of the pentanol was found to be 4,320, and the peak area of the hexanol was found to be 4,156. When an unknown was run, a solution containing 1.00 mL of the unknown pentanol was mixed with 5 mL of 1.42 mM hexanol, and the resulting solution was diluted to 10.0 mL. The area of the pentanol peak was found to be 2,250 and the hexanol 5,450. Calculate the concentration (in mM) of pentanol in the unknown.
