The partial pressure of carbon dioxide in a mixture is 0.31 atm.
juin [17]

Answer:

P_{Co2}= X_{Co2} P_{tot}

Where P_{tot} represent the total pressure and X_{Co2} the fraction of carbon dioxide is 0.46 and we can find the total pressure with this formula:

P_{tot}= \frac{P_{Co2}}{X_{Co2}}

And replacing we got:

P_{tot}= \frac{0.31 atm}{0.46}= 0.674 atm

Step-by-step explanation:

For this case the partial presure of carbon dioxide is given by:

P_{Co2}= X_{Co2} P_{tot}

Where P_{tot} represent the total pressure and x_{Co2} the fraction of carbon dioxide is 0.46 and we can find the total pressure with this formula:

P_{tot}= \frac{P_{Co2}}{X_{Co2}}

And replacing we got:

P_{tot}= \frac{0.31 atm}{0.46}= 0.674 atm
