Convert a number concentration of 15 X 10^12 molecule/cm3 into volume mixing ratio at:
a) 1 atm pressure, and 20 C temperature.
b) 500 mbar pressure, and 253 K temperature.
Using the Ideal Gas Law, calculate:
a) Loshmidt’s number (# of molecules/cm3 of air, at standard atmospheric conditions “STP”, 1 atm pressure, and 273 K)
b) Density of atmosphere at “STP”
The Attempt at a Solution[/B]
I converted 15 x 10^12 molecule/cm^3 to mol/cm^3
