Pheromones are substances secreted by females of many insect species to attract mates. Typically, 1 x 108 g of a pheromone is sufficient to reach all targeted males
within a radius of 0.4 miles. Calculate the density of the pheromone, in g/L, in a
cylindrical air space having a radius of 0.4 miles and a height of 40 ft. The volume
of a cylinder can be found by applying the formula V = itrah
