Actives in a tablet. Tolbutamide, a drug sold under the brand name Orinase, is used in the management of type II diabetes if diet alone is not effective. Tolbutamide has a molar absorptivity ( \( \varepsilon \) ) of \( 703 \mathrm{~L} \mathrm{~mol}^{-1} \mathrm{~cm}^{-1} \) at \( 262 \mathrm{~nm} \). One tablet dissolved in water and diluted to a volume of 2 litres gave a solution with an absorbance of \( 0.687 \) in a \( 1 \mathrm{~cm} \) cell at \( 262 \mathrm{~nm} \). How many grams of the drug are contained in the tablet?
