(a) Carbon monoxide (CO) is a poisonous gas because it binds very strongly to the oxygen carrier hemoglobin in blood. A concentration of $8.00 \times 10^{2}$ ppm by volume of carbon monoxide is considered lethal to humans. Calculate the volume in liters occupied by carbon monoxide in a room that measures $17.6 \mathrm{m}$ long, $8.80 \mathrm{m}$ wide, and $2.64 \mathrm{m}$ high at this concentration. (b) Prolonged exposure to mercury (Hg) vapor can cause neurological disorders and respiratory problems. For safe air quality control, the concentration of mercury vapor must be under 0.050 $\mathrm{mg} / \mathrm{m}^{3} .$ Convert this number to g/L. (c) The general test for type II diabetes is that the blood sugar (glucose) level should be below $120 \mathrm{mg}$ per deciliter $(\mathrm{mg} / \mathrm{dL}) .$ Convert this number to micrograms per milliliter $(\mu \mathrm{g} / \mathrm{mL}).$

Chemistry is the science of matter, especially its chemical reactions, but also its composition, structure and properties. Chemistry deals with atoms and their interactions with other atoms, and particularly with the properties of chemical bonds. Chemistry also involves understanding the properties and interactions of individual atoms and molecules for use in larger-scale applications.

In chemistry and physics, matter is any substance that has mass and takes up space by having volume. All everyday objects that can be touched are ultimately composed of atoms, which are made up of interacting subatomic particles, and in everyday as well as scientific usage, "matter" generally includes atoms and anything made up of them, and any particles and objects that act as if they have both rest mass and volume. However it does not include massless particles such as photons, or other energy phenomena or waves such as light or sound. Matter exists in various states (known as phases) that are defined by various physical properties, such as state of matter, phase, shape, and density. The Standard Model of particle physics and the general theory of relativity describe fundamental particles and the fundamental forces acting between them that control the structure and dynamics of matter.

We'll start with vendors for the length of the width and height of the room to give us meters cubed. Then knowing meters cubed, we can take the parts per 1,000,000 by volume and use any volume unit we want. So whatever volume unit we choose will be 8.0 Tend to the to of those units her one million of those units. We'll take our ungrounded number here in meters cubed and we'll have 800 meters cubed of carbon monoxide for every 1,000,000 meters cubed of air. This then becomes our conversion factor to allow us to convert the volume of the air to the volume of carbon monoxide 0.3 to 5 meters cubed. But it asks for the answer in units of leaders. So we'll take our meters cubed and converted two centimeters cube and then our centimeters cubed into leaders and we get 325 leaders when we don't do any rounding until the very end. For the next part of this problem, we have 0.50 milligrams per meter, cubed as the concentration of mercury, my three vapor, and it asks us to convert the milligrams per meter cubed two grams for leader, so we can easily convert the milligrams two grams using 1000 to 1 and then the meters cubed will do something similar to what we did up here. For every one meter there is 100 centimeters, but we need a cube apt to go from meters cube to centimeters tube and then for every 1000 centimeters cube. We have a leader and we've got the leaders down below because we want the volume in the denominator and we'll get 5.0. Attended the negative eight crams for leader Been for the last part of this problem. The blood sugar level of 120 milligrams per decile leader of glucose needs to be converted into micrograms per mil leader milligrams per the milligrams converted to micrograms is pretty straightforward. You could convert milligrams into grams and then grams into micrograms or recognize that milligram is 10 to the negative. Three Micro is 10 to the negative six, so there's a 10 10 to the negative three difference between the two. So there's 10. There's 1000 micrograms for everyone milligram, then for Desa liters again, we could go from Decile eater two leader and then leaders into milliliters. Or we could recognize that a decile eaters tend of the negative one A. Middle leaders tended to give three, so that's a difference of 10 to the to. So for everyone, DESA leader, there is 10 of the two 100 milliliters and we get 1200 micrograms per mil leader.
