Answer #1

Beer-Lambert law

A = c l

Here

A = Absorbance, (given in question = 0.591)

c = concentration of the solution, expressed in mol/L (? = have to calculate)

= absorption coefficient of the absorbing medium, expressed in(mol/L)-1 cm-1.

(It is charecteristic of the solute and depends upon the nature of the solvent, temperature and the wavelength of the radiation employed.

l = path length, expressed in cm

Without knowing and l, its not possible to calculate the concentration.
