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. How many liters of air does a person breathe in Utah County in 8 hours? How many liters of carbon monoxide will a person breathe in Utah County in 8 hours? How many milligrams of carbon monoxide would a person in Utah County inhale in an 8 hours?

To do this, you should consider the price per degree of dropping the temperature of the solution. The table of prices per kg for each salt is shown above. Let's determine the cost for the NaOH solid as an example. We want to determine how much it costs to change the temperature by 1 deg C so we start with the cost given in the table and end with $/deg C. For NaOH: 21.17 $/ 1 kg) X ( 1 kg/ 1000 X ( Type your answer here g/ Type your answer here deg C) Please type your answer to submit Please type your answer to submit Type your answer here $/deg C

The U.S. Government has about 1.23 * 107 pounds of gold in Fort Knox. How much is it worth at today's value of $1,576.30 per Troy ounce?  Given: 12 Toz = 1 Lb Group of answer choices I honestly do not know; however, if it were not for James Bond, the Goldfinger would have stolen all of it. $1.94 * 10^10 US dollars $2.33 * 10^11 US dollars $ 4.30 * 10^-12 US dollars
