Air has mass and density, and. cold air is denser than warm air.
The same amount of water as oil air
Answer:
![P_{CCl_4}=52.43torr](https://tex.z-dn.net/?f=P_%7BCCl_4%7D%3D52.43torr)
Explanation:
Hello there!
In this case, sine the solution of this problem require the application of the Raoult's law, assuming heptane is a nonvolatile solute, so we can write:
![P_{CCl_4}=x_{CCl_4}P_{CCl_4}^{vap}](https://tex.z-dn.net/?f=P_%7BCCl_4%7D%3Dx_%7BCCl_4%7DP_%7BCCl_4%7D%5E%7Bvap%7D)
Thus, we first calculate the mole fraction of chloroform, by using the given masses and molar masses as shown below:
![x_{CCl_4}=\frac{140/153.81}{140/153.81+67.1/100.21}=0.576](https://tex.z-dn.net/?f=x_%7BCCl_4%7D%3D%5Cfrac%7B140%2F153.81%7D%7B140%2F153.81%2B67.1%2F100.21%7D%3D0.576)
Therefore, the partial pressure of chloroform turns out to be:
![P_{CCl_4}=0.576*91torr\\\\P_{CCl_4}=52.43torr](https://tex.z-dn.net/?f=P_%7BCCl_4%7D%3D0.576%2A91torr%5C%5C%5C%5CP_%7BCCl_4%7D%3D52.43torr)

1) 100s of millions of years ago Trees and plants fall into swamps
2) Layers of rotting plant matter builds up underwater
3) Over millions of years the weight of layers heat the plant matter and turn into Peat
4) Over millions of years more pressure and heat turns Peat into coal
