Final Answer :
B
Explanation :
The total pressure of the air is the sum of the partial pressures of all its components. Given that the total pressure is 1.10 atm and the air is composed of 0.8 atm nitrogen and 0.25 atm oxygen, the partial pressure of CO2 can be found by subtracting the sum of the nitrogen and oxygen pressures from the total pressure: 1.10 atm - (0.8 atm + 0.25 atm) = 0.05 atm.
