Vanillin (used to flavor vanilla ice cream and other foods) is the substance whose aroma the human
nose detects in the smallest amount. The threshold limit is 2.0 × 10-11 g per liter of air. If the
current price of 50.0 g of vanillin is $111, determine the cost to supply enough vanillin so that the
aroma could be detected in a large aircraft hangar with a volume of 5.35 x 107 ft³.
