1. A container holds four times as many moles of CO2 as O2. If the total pressure in the container is 20. atm,

what is the pressure exerted by carbon dioxide?

T

-

atm

Round your answer to the nearest whole number.

Partial pressure of CO2 = 16 atm

Explanation:

Total number of moles of gases = 4+1 = 5 moles

Mole fraction of CO2 = 4/5

Partial pressure of CO2 = mole fraction of CO2 * total pressure

Partial pressure of CO2 = (4/5) * 20

Partial pressure of CO2 = 16 atm
