25.0 g of an impure sample containing cobalt was dissolved in acid and diluted to 1000.00 mL. 6.00 mL of this sample was removed, treated appropriately to give a colored solution, and then diluted to 250.00 mL. This final solution had an absorbance of 0.410. Calculate the percentage of cobalt (MW = 58.93 g/mol) in the original sample.
