Answer:
[tex]P_{CO_2}=25mmHg[/tex]
Explanation:
Hello there!
In this case, according to the Dalton's law, which explains that the total pressure of a gaseous system equals the sum of the partial pressures of the gases composing, for the gaseous mixture composed by oxygen, nitrogen and carbon dioxide it would be possible to write:
[tex]P_{tot}=P_{N_2}+P_{O_2}+P_{CO_2}[/tex]
Now, given the pressure of the system and those of oxygen and nitrogen, we calculate that of carbon dioxide as shown below:
[tex]P_{CO_2}=P_{tot}-P_{N_2}-P_{O_2}\\\\P_{CO_2}=250mmHg-50mmHg-175mmHg\\\\P_{CO_2}=25mmHg[/tex]
Best regards!
