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
The difference between the amount of oxygen inhaled and exhaled is:
22.85 mL - 4.57 mL = 18.28 mL
To calculate the difference between the amount of oxygen inhaled and exhaled, subtract the amount of oxygen exhaled from the amount of oxygen inhaled.
Amount of oxygen inhaled = 22.85 mL
Amount of oxygen exhaled = 4.57 mL
Difference = Amount of oxygen inhaled - Amount of oxygen exhaled
Difference = 22.85 mL - 4.57 mL
Difference = 18.28 mL
Therefore, the difference between the amount of oxygen inhaled and the amount of oxygen exhaled is 18.28 mL.
