A solution of a dye absorbs light of wavelength 480 nm, and for this absorption, the extinction coefficient is 18600 L/mol/cm. A sample of the dye of unknown concentration is placed in an optical cell of bath length 1 cm and the absorbance reading is 0.18. What is the concentration of the solution?

28. which is not a reason that water is used to store spent fuel rods from nuclear power plants? water increases the speed of the chain reaction in the fuel rods. water protects nuclear power plant workers from the high temperature and radiation of the fuel rods. water acts as a radiation shield to reduce the radiation levels. water cools the spent rods. salts action
