Vanillin (used to flavour 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 x 10-11 gram 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 detectable in a large aircraft hangar of volume 5.0 x 107 ft3.
