The difference between the amount of oxygen inhaled and exhaled is:
22.85 mL - 4.57 mL = 18.28 mL
The table shows data about the percentages of gases in air inhaled and exhaled. The gases are oxygen (O2), nitrogen (N2), and carbon dioxide (CO2).
Assume the volume of air inhaled and exhaled is 500 mL. Calculate the difference (in mL) between the amount of oxygen inhaled and the amount of oxygen exhaled.
22.85 mL of oxygen
4.57 mL of oxygen
104.7 mL of oxygen
81.85 mL of oxygen
