QUESTION:
In the average adult male, the residual volume (RV) of the lungs, the volume of air remaining after a forced exhalation, is 1200 mL. (a) How many moles of air are present in the RV at 1.0 atm and 37_C? (b) How many molecules of gas are present under these conditions?
ANSWER:Step 1 of 3
The ideal gas law can be given as:
Here, is the universal gas constant.
The number of moles of air at 1 atm can be found as:
Where n denotes the number of moles, P denotes the pressure, V is the volume 1200 mL and T is the temperature, or 310 K.
