Chapter 1, Problem 112AP

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 $2.0\times {10}^{-11}$ g per liter of air. If the current price of 50 g of vanillin is $112. determine the cost to supply enough vanillin so that the aroma could be detected in a large aircraft hangar with a volume of $\text{5}{\text{.0 × 10}}^{\text{7}}{\text{ ft}}^{\text{3}}$.
