Be sure to answer all parts. Pheromones are compounds secreted by females of many insect species to attract mates. Typically, 1.00 × 10−8 g of a pheromone is sufficient to reach all targeted males within a radius of 0.500 mi. Calculate the density of the pheromone (in grams per liter) in a cylindrical air space having a radius of 0.500 mi and a height of 33.0 ft (volume of a cylinder of radius r and height h is πr2h).

Matter and Measurement

In the universe, there is matter, energy, and void space. The universe contains energy and void space. The definition of matter can be considered as something which possesses mass and consumes space. Chemistry is that branch of science which deals with the study of matter. Under chemistry, nature, composition, and the changes occurring to matter are discussed.
