Question
Observe yourself breathing and count the number of times you inhale per second. During each breath you probably inhale 0.48L of air. Assume the pressure is 1 atm and the temperature is 20?C. Only about 21% of air is O2. How many oxygen molecules do you inhale if you are at sea level?Observe yourself breathing and count the number of times you inhale per second.

Explanation / Answer
n= PV/RT = 1*0.48/(0.0821*293)= 0.0199 moles
==> moles of oxygen = 21% 0f 0.0199
==> molecules of Oxygen = 0.21*0.0199*6.022E23 = 2.516 E21 molecules
