Suppose you need to prepare a set of calibration standards for the spectrophotometric analysis of acetone at a wavelength of 211 nm using a 1.00 cm cell. The molar absorptivity for acetone at this wavelength is 562. To maintain an acceptable precision for the analysis you wish to keep the %T for your standards between 15% and 85%. What is the most concentrated and the least concentrated standard that you would want to prepare for this analysis?
