Answer:
<em>The volume of the air breath per day is =12240 L day ^ -1 and he volume of oxygen breathe each day is= 2570.4 L</em>
Explanation:
<em>Complete question: </em><em>The oxidizing agent our bodies use to obtain energy from food is oxygen (from the air). If you breathe 17 times a minute (at rest), taking in and exhaling 0.50 L of air with each breath, what volume of air do you breathe each day? Air is 21% oxygen by volume. what volume of oxygen do you breathe each day?</em>
<em>Solution</em>
<em>Given that,</em>
<em>The volume of the air with each breath = 0.50L</em>
<em>The frequency of breath is = 17 times per minute</em>
<em>the next step is to calculate the volume of the air breath per day</em>
<em>The volume of the breathed air = volume of air breathed/ breath * 17 breaths/min * 60 minutes / per hour * 24 hours/ per day</em>
<em>= 0.50L/ breath * 17 breath /min * 60 minutes / per hour * 24 hours/ per day</em>
<em>= 12240 L day ^ -1</em>
<em>The next step is to calculate the oxygen breathed per day:</em>
<em>The volume of oxygen breathed = volume of air breathed * percent oxygen in air/100</em>
<em>= 12240 L day ^ -1 * 21 /100</em>
<em>= 2570.4 L day ^ -1 </em>
<em>Therefore for each day, the volume of oxygen breathe is 2570.4 L</em>
