A certain mass of a compound with a formula mass of 134.40 g/mol was dissolved in a 50.00 mL volumetric flask. A 1.00 mL aliquot was withdrawn and placed in a 10.00 mL volumetric flask. The absorbance was measured in a 0.500 cm cuvette and found to be 0.811. The molar absorptivity for this compound is 2881 M-1cm-1. How many mg of compound were used to make the 50.00 mL solution?
