Answer :
The pressure of carbon dioxide in the atmosphere in mmHg is 0.239mmHg.
The pressure of carbon dioxide in the atmosphere in atm is
.
Explanation :
The conversion used for pressure from torr to mmHg is:
1 torr = 1 mmHg
The conversion used pressure from torr to atm is:
1 atm = 760 torr
or,
![1torr=\frac{1}{760}atm](https://tex.z-dn.net/?f=1torr%3D%5Cfrac%7B1%7D%7B760%7Datm)
As we are given the pressure of carbon dioxide in the atmosphere 0.239 torr. Now we have to determine the pressure of carbon dioxide in the atmosphere in mmHg and atm.
<u>Pressure in mmHg :</u>
As, ![1torr=1mmHg](https://tex.z-dn.net/?f=1torr%3D1mmHg)
So, ![0.239torr=\frac{0.239torr}{1torr}\times 1mmHg=0.239mmHg](https://tex.z-dn.net/?f=0.239torr%3D%5Cfrac%7B0.239torr%7D%7B1torr%7D%5Ctimes%201mmHg%3D0.239mmHg)
Thus, the pressure of carbon dioxide in the atmosphere in mmHg is 0.239mmHg.
<u>Pressure in atm:</u>
As, ![1torr=\frac{1}{760}atm](https://tex.z-dn.net/?f=1torr%3D%5Cfrac%7B1%7D%7B760%7Datm)
So, ![0.239torr=\frac{0.239torr}{1torr}\times \frac{1}{760}atm=3.14\times 10^{-4}atm](https://tex.z-dn.net/?f=0.239torr%3D%5Cfrac%7B0.239torr%7D%7B1torr%7D%5Ctimes%20%5Cfrac%7B1%7D%7B760%7Datm%3D3.14%5Ctimes%2010%5E%7B-4%7Datm)
Thus, the pressure of carbon dioxide in the atmosphere in atm is
