Answer 1

The original air present after 8 breaths will be equal to 179.81 ml.

What is an equation?

The equation in mathematics is the relationship between the variables and the number and establishes the relationship between the two or more variables.

It is given in the question that:-

During normal breathing, about 12% of the air in the lungs is replaced after one breath

If the initial amount of air in the lungs is 500 mL

how much of the original air is present after 8 breaths?

The calculation for the eduction of the air will be done by the following equation:-

$\rm =Volume \ present\times (0.88)^n\\\\\\= 500\times (0.88)^8$

=179.88 ml

Hence original air present after 8 breaths will be equal to 179.81 ml.
