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?

You are working with a colleague to measure the carbonate chemistry of a set of water samples. Unfortunately your colleague is a bit sloppy, and when you look at the data, you realize there must have been some errors in the measurements. Blank cells in the table below mean your colleague didn't collect data for that species in that sample. For each sample (#1-6), EITHER explain why at least some measurements for that sample must be in error OR fill in the missing data with reasonable values. (Note: you can assume the precision of the measurements is ±1mM, so inconsistencies below that level do not necessarily indicate errors.)
