The answer is D. Distilling.
Answer:
19.61kg
Explanation:
The first thing to do is divide the amount of feet into 3.28:
![18ft*12ft*8ft=5.49m*3.66m*2.44m](https://tex.z-dn.net/?f=18ft%2A12ft%2A8ft%3D5.49m%2A3.66m%2A2.44m)
With this information, we calculate the volume:
![V=5.49m*3.66m*2.44m=49.03m^{3}](https://tex.z-dn.net/?f=V%3D5.49m%2A3.66m%2A2.44m%3D49.03m%5E%7B3%7D)
As we have the concentration and the volume, we can calculate the mass of CO:
![m=400,000 \mu g/m^{3}*49.03m^{3}=19611158.4 \mu g](https://tex.z-dn.net/?f=m%3D400%2C000%20%5Cmu%20g%2Fm%5E%7B3%7D%2A49.03m%5E%7B3%7D%3D19611158.4%20%5Cmu%20g)
As this is a very big number, we can express it in kg by dividing in 10^6:
![19611158.4 \mu g/10^{6}=19.61 kg](https://tex.z-dn.net/?f=19611158.4%20%5Cmu%20g%2F10%5E%7B6%7D%3D19.61%20kg)
Answer:
Everything in Earth's system can be placed into one of four major subsystems: land, water, living things, or air. These four subsystems are called "spheres." Specifically, they are the "lithosphere" (land), "hydrosphere" (water), "biosphere" (living things), and "atmosphere" (air).

Sea turtles they leave them on the beach
