The average person takes 500 mL of air into the lungs with each normal inhalation, which corresponds to approximately 1X10²² molecules of air. Calculate the number of molecules of air inhaled by a person with a respiratory problem who takes in only 350 mL of air with each breath. Assume constant pressure and temperature.

Respuesta :

The number of molecules of air inhaled by a person with a respiratory problem who takes in only 350 mL of air with each breath is 7 X 10^21.

What is mole?

Mole is defined as the ratio of given mass to the molar mass of the substance.

Moles = given mass/ molar mass

It can also be said that,

Number of moles = Number of molecules/ Avagadro Number

(m2/A) = V2(m1/A) / V1

m2 = V2× m1/ V1

Given,

Volume of gas inhaled = 350mL. = V2

Average volume of gas inhaled = 500mL.= V1

Number of molecules = 1X10²² = m1

By substituting all the values in given equation, we get

m2 = 350mL × 1X10²²/ 500mL

m2 = 7 X 10^21.

Thus, we calculated that the number of molecules of air inhaled by a person with a respiratory problem who takes in only 350 mL of air with each breath is 7 X 10^21.
