A)how would you prepare 250 ml of a 0,150 m solution of CoCl2 from solid CoCl2 and distilled water?
b)using the solution from part a and ditilled water,how would you prepare 100 ml of a 0.0600m solution of CoCl2?
c)What absorbance would you expect from the solution from part b at the wavelength of maximum sensitivity?
