The cosmetics company you work for wants to get ahead of climate change by making a sunscreen that is SPF 5000. The SPF 30 product contains 0.44 M avobenzone (MW=310.39 g/mol) and has an absorbance of 0.2 at the wavelength of interest. They want you to increase the absorbance of the avobenzone to 1.3. What should be the new concentration of avobenzone? Show your work.
