3. A red dye absorbs most effectively in the range of 500-525nm.
6. The equation used for volumetric dilution is:
C1V1= C2V2 where C1= concentration of stock solution, V1= volume of stock solution needed to make new solution, V2= Volume of new solution, using all these values the concentration of new solution C2 can be found.
