A solution mixture contains aqueous M⁺³ and N⁺² cations. They both have absorbance spectra that overlap. The molar absorptivity coeffecients (s) for M⁺³ are 4.8M⁻¹cm⁻¹ (at 450 nm ) and 16.3 M⁻¹cm⁻¹ (at 610 nm ) whereas the molar absorptivity coeffecients ( ε ) for N⁺² are ) and 3.2M⁻¹cm⁻¹ (at 610 nm ). If the Absorance of the solution mixture at 450 nm is 0.336 and at 610 nm is 0.808 , then determine the Concentration of N⁺² in mmo l/L.
