Kinetic theory of gases

Average number of molecule's encounters

average number of encounters  = 1/s x 1/s molecule diameter d = m x Å nm μm mm cm dm m km n mile in ft yd average velocity of molecules  = m/s x m/s km/h cm/s ft/s kn gas density ρ = kg/m3 x kg/m3 kg/dm3 g/cm3 t/m3 kg/l3 g/l3 g/ml3 Avogadro number Na = 6.022E23 1/mol molar mass M = kg/mol x g/mol kg/mol
