Question

A chamber contains equal molar amounts of CO, CO2, N2, and O2. If the total chamber pressure is 3.00 atm, then the partial pressure of CO2 is

Answer 1

Answer:

$P_{CO_2} = 0.75 atm$

Explanation:

$P_{total} = P_{CO} + P_{CO_2} + P_{N_2} + P_{O_2}$

Since there's equal molar amounts we can conclude that

$P_{CO_2} = P_{CO} = P_{N_2} = P_{O_2}$

So,

$P_{total} = 4P_{CO_2}\\3.00 atm = 4P_{CO_2}\\P_{CO_2} = \frac{3.00 atm}{4} = 0.75 atm$
