In 2014 (the last year for which I can find data), Utah County had a carbon monoxide (CO) average concentration of 1.90 ppm. (1 ppm stands for 1 part per million which means in one million volumes of air—choose whatever volume unit you like—there would be one volume of carbon monoxide.) An average human takes inhales 0.50 L per breath and takes 20 breaths per minute. Carbon monoxide in the atmosphere has a density of 1.2 grams per liter. 3. How many milligrams of carbon monoxide would a person in Utah County inhale in an 8 hours?

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.
