Question: Two solutions A and B have the same molar absorption coefficient at 260 nm: 1.80 x 10^4 dm^3 m^-1 cm^-1. At 340 nm A no

Two solutions A and B have the same molar absorption coefficient at 260 nm: 1.80 x 10^4 dm^3 m^-1 cm^-1. At 340 nm A no longer absorbs and for B B= 6.22 x 10^3 dm^3 m^-1 cm^-1. A solution of both has an absorbance of 0.215 at 340 nm and 0.850 at 1 260 nm in a 1 cm thick cell. Calculate A and B concentrations.
