A solution was prepared using 0.0010 g of an unknown steroid (of molecular weight around 255) in 100 mL of ethanol. Some of this solution was placed in a 1-cm cell, and the UV spectrum was measured. This solution was found to have ?max = 235 nm, with A = 0.74.
(a) Compute the value of the molar absorptivity at 235 nm.
(b) Which of the following compounds might give this spectrum?
