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
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.
