The average lung capacity of a human is 6.0l.
how many moles of air are in your lungs, when you are in the following situations?
(a) at sea level where t=298 k, and p = 1.00 atm.
(b) on top of mt everest where t = 200 k and p = 0.296 atm.
(c) trying to escape from a sunken submarine where t = 250 k and p = 30 atm.

(a) 0.25 mol

(b) 0.11 mol

(c) 8.77 mol

Explanation:

(a)

We use the equation given by ideal gas which follows:

where,

P = pressure of the gas = 1.00 atm

V = Volume of the gas = 6.0 L

T = Temperature of the gas = 298 K

R = Gas constant =

n = number of moles = ?

Putting values in above equation, we get:

(b)

We use the equation given by ideal gas which follows:

where,

P = pressure of the gas = 0.296 atm

V = Volume of the gas = 6.0 L

T = Temperature of the gas = 200 K

R = Gas constant =

n = number of moles = ?

Putting values in above equation, we get:

(c)

We use the equation given by ideal gas which follows:

where,

P = pressure of the gas = 30 atm

V = Volume of the gas = 6.0 L

T = Temperature of the gas = 250 K

R = Gas constant =

n = number of moles = ?

Putting values in above equation, we get:
