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. a. 22.85 ml of oxygen b. 4.57 ml of oxygen c. 104.7 ml of oxygen d. 81.85 ml of oxygen

A. 22.85 mL of oxygen

Explanation:

Data:

The total volume of Oxygen =500 mL.

Percentage of Oxygen inhaled= 20.94 %

Amount of Oxygen inhaled =20.94 /100 x500 ml

                                            =104.7 ml

Percentage of Oxygen exhaled = 16.37 %

Amount of Oxygen inhaled =16.37 /100 x500 ml

                                              =81.85 ml

Difference  b/w amount of oxygen inhaled/exhaled= 104.7 ml-81.85 ml

                                            =22.85 ml

Therefore, Option A is correct option.

Hope it help!
