Vanillin (used to lavor vanilla ice cream and other foods) is the substance whose aroma the human nose detects in the smallest amount. The threshold limit is2.010"g per liter of air. If the current price of 50.0 g of vanillin is Slll, determine the cost to supply enough vanillin so that the aroma could be detected in a large aircraft hangar with a volume of 5.37X10 f Report problem Hint Solution points Book Guided Solution References

Explanation / Answer

threshold limit = 2.0*10^-11 g / liter

cost = 50 g / 111 $

so cost for 1 g = 111/50 = 2.22 $

volume of aircraft hanger = 5.37 * 10^7 ft^3

= 5.37*10^7 * 28.3168 liter ( 1 ft^3 = 28.3168 liter )

= 152.06 *10^7 liter

= 1.5206 *10^9 liter

minimum amount of vanilin needed for detection

= 2.0*10^-11 * 1.5206 *10^9

= 3.04*10^-2 g

so the minimum cost for vanilin = 2.22*3.04*10^-2

= 6.69*10^-2 $

so the minimum cost to supply enough vanilin = 6.69*10^-2 $
