Problem- A 3.96 x 10-4 M solution of compound A exhibited an absorbance of 0.624 at 238nm in a 1.00 cm cuvet; a blank solution containing only solvent has an absorbance of 0.029 at the same wavelength. A unknown solution of compound A in the same solvent was diluted from an initial volume of 2.00mL to 25.00mL and had an absorbance of 0.733 at 238 nm in a 1.00 cm cuvet. What is the concentration of the unknown solution?
