I. Solution I is 0.088 M in compound Z and has an absorbance of 0.203 in a 1 cm cell at 520 nm. The solvent alone has an absorption of 0.084 in the same cell. What is the concentration of Z in solution II if the absorbance of solution II in the same cell and at the same wavelength is 0.377?

II. Suppose a mixture of two solutions is prepared by mixing 105.-mL of 0.0335 M solution with 35.0-mL of 0.932 M of the same solute (Z). What is the concentration of Z in the combined solution?
