The drug tolbutamide (MW 270.0g/mol), a treatment for type 2 diabetes, has a molar absorptivity of 703 /M/cm at 262nm. One tablet was dissolved in 250ml of water. A 10.0 ml aliquot of this solution was diluted to 100.00 ml in a volumetric flask. This diluted solution exhibited an absorbance of 0.275 at 262 nm in a 1.00 cm cell. What is the mass of tolbutamide in the tablet?
