Air enters in the lungs in a tiny cavity called alveoli. Oxygen diffuses into our blood from alveoli. The average radius of alveoli is 0.005 cm and air inside it contains 21% `O_(2)` and 79% `N_(2)`. Assuming that the pressure in the aveoli is 1 atm at body temperature of `37^(@)C`.
Volume of single alveoli is :
A. `5.23 xx 10^(-7) cm^(3)`
B. `5.23 xx 10^(-9) cm^(3)`
C. `5.23 xx 10^(-6) cm^(3)`
D. `5.23 xx 10^(-8) cm^(3)`
