Avobenzone is used in sunscreens. A UV spectrum of a 2.0 mL sample of avobenzone (310.4 g/mol) in a 1.0 cm cell was obtained. The molar extinction coefficient for avobenzone is 9120 M⁻¹cm⁻¹. The UV spectrum revealed a λ(max) of 300 nm with an absorbance of 0.80. Calculate the mass of avobenzone in the solution.
