A compound with a molecular mass of 842.45 was dissolved in a 45.0 mL volumetric flask. A 10.00 mL aliquot was withdrawn, placed in a 50.0 mL volumetric flask, and diluted to the mark. The absorbance at 550 nm was 0.627 in a 1.000 cm cuvet. The molar absorptivity for this compound at 550 nm is ₅₅₀ = 9510 M^-1cm^-1. Determine the concentration of the compound in the cuvet, the concentration of the compound in the 45 mL flask and the number of milligrams that were used to make the 45 mL solution.
