Asked by Ricky
If the pressure exerted by ozone, O3, in the stratosphere is 3.0 x 10^-3 atm and the temperature is 250K, how many ozone molecules are in a liter?
Please help me.

P V = n R T
P in atm
V in liters
T in deg K
R = 0.082 L atm K mol^-1
from
http://www.cpp.edu/~lllee/gasconstant.pdf
3.0*10^-3 * 1 = n (.082)(250)
n = do the calculation for n, the number of mols
then
multiply by Avagadro's number, the number of molecules per mol
