A 20 mM solution of ethanol is diluted 1 in 8. The diluted ethanol solution was used for an alcoholdehydrogenase assay that had a total volume of 1.5 mL. 20 μL of alcoholdehydrogenase was used for the assay. The reaction was followed spectrophotometrically and a progress curve plotted from the spectrophotometric data. Using the progress curve, the initial velocity was calculated as 0.30 AA/min. The assay was repeated as above, with a different volume of alcoholdehydrogenase. The initial velocity was 0.01 AA/s. What volume (in µL) of alcoholdehydrogenase was used for the assay? (do not include units in the answer
