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 (volume of a cylinder of radius r and height h is ïr2h).

Density of pheromones compound is .

Explanation:

Mass of pheromones compound =

When pheromone is in a cylindrical air space having a radius of 0.50 mi and a height of 40 ft.The volume of the cylindrical air space will be given by:

Radius of the cylindrical air space,r =  0.50 mile = 804.672 m

Height of the cylindrical air space,h =  40 feet = 0.00757576 mile =12.1920 m

Density of pheromones compound:

it should be p1 v1 = p2 v2

the answer your looking for is c).
