Question:

Pheromones are compounds secreted by females of many insect species to attract mates. Typically, 1.0 x 10-8 g of a pheromone is sufficient to reach all targeted males within a radius of 0.50 mi. Calculate the density of the pheromone (in grams per liter) in a cylindrical air space having a radius of 0.50 mi and a height of 40 ft.
