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?

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

Explanation:

Complete question: 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?

Solution

Given that,

The volume of the air with each breath = 0.50L

The frequency of breath is = 17 times per minute

the next step is to calculate the volume of the air breath per day

The volume of the breathed air = volume of air breathed/ breath * 17 breaths/min * 60 minutes / per hour * 24 hours/ per day

= 0.50L/ breath * 17 breath /min * 60 minutes / per hour * 24 hours/ per day

= 12240 L day ^ -1

The next step is to calculate the oxygen breathed per day:

The volume of oxygen breathed = volume of air breathed * percent oxygen in air/100

= 12240 L day ^ -1 * 21 /100

= 2570.4 L day ^ -1

Therefore for each day, the volume of oxygen breathe is 2570.4 L

the correct option is c.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.
