Step 1
- Given: Volume of expired air in 5 minutes = 30 liters - Percentage of CO$_2$ in expired air = 4.2% \[ \text{Volume of CO}_2 = \left( \frac{4.2}{100} \right) \times 30 \text{ liters} \] \[ \text{Volume of CO}_2 = 0.042 \times 30 \text{ liters} \] \[ Show more…

Calculate the volume of air in liters that you might inhale (and exhale) in a 24-hour day. Assume that each breath has a volume of about 0.5 L, and that you are breathing 15 times a minute. (If possible, show your calculation) (4 pts) 3. From this calculation (above), you can see that breathing exposes you to large volumes of air. Identify 3 sources of particulate matter found in air (3 pts) 1. 2. 3.

(a) Calculate the volume of air in liters that you would inhale in 24 hours assuming that you inhaled 16 breaths per minute and each breath had a volume of approximately $0.50 \mathrm{~L} .\left(T=18.0^{\circ} \mathrm{C} ; P=0.970 \mathrm{~atm} .\right)$ (b) Compare that total volume to the volume of air in a typical residence hall room, approximately $864 \mathrm{ft}^{3}$ (approx. $\left.28 \mathrm{~L} / \mathrm{ft}^{3}\right)$ (c) Calculate the number of oxygen molecules you inhaled during that time.
