A pheromone is a type of volatile compound produced by a variety of insect species for chemical communication. These molecules can be used to signal alarm, to attract a mate, or to indicate the presence of food. The presence of 1.20 × 10⁻⁸ g of a pheromone can be sensed by another insect within a radius of 0.500 miles. Calculate the density of this pheromone. (1609 m = 1 mile) Assume that the area that a pheromone can be sensed is a cylindrical air space. Calculate the volume of this air space assuming a radius of 0.500 mi and a height of 40.0 ft.
