The theoretical molar absorptivity for β-carotene is over 100,000 L/(mol·cm). Your calculated molar absorptivity for β-carotene will be lower than this because a fraction of the β-carotene did not dissolve in the cyclohexane. Explain why the molar absorptivity of β-carotene is still orders of magnitude greater than that any of the others measured?
