A metal complex with a Molecular mass of 820 g mol−1 was dissolved and the solution made up to 25 mL in a volumetric flask. 1 mL was withdrawn, placed in a 100 mL volumetric flask and diluted to the mark. The absorbance (at 457 nm) of this solution (in a 1 cm cuvette) was 0.245. The extinction coefficient for this compound at 457 nm (ε530) = 11715 M-1cm-1. (a) calculate the concentration of the compound in the cuvette. (b) calculate the concentration of the compound in the 25mL volumetric flask (c) determine the mass of compound used to make the 25mL solution
