Question

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.

Answer 1

Partial pressure of CO2 = 16 atm

Step-by-step 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
