Question

The process illustrated here is somewhat different from those we have been studying, because the pressure change is due to changes in the amount of gas in the lung, not to temperature changes. (Think of your own breathing. Your lungs do not expand because they've gotten hot.) If the temperature of the air in the lung remains a reasonable 20 ∘C, what is the maximum number of moles in this person's lung during a breath?

Answer 1

Answer:

5.9 × 10^-2 mol.

Explanation:

PLEASE NOTE: The Question is not complete, kindly check the question's comment section for the remaining part of the question and also, the graph(part of the question) below.

The number of moles in this question or problem can be determined or can be calculated as given below. Recall that 1 litre = 1/1000 m^3, The Standard Atmospheric Pressure =  1.013 × 10^5 N/m^2 = 760 mmHg.

Thus, the number of moles = ( 771 / 760 ) × 1.4 × 1.013 × 10^5 × ( 1/1000 m^3).

The number of moles = 5.9 × 10^-2 mol.

[NB: the 1.4 can be traced on the graph]
