P = \frac{F}{A}

p = h ρ g

P V = n R T

P_{T} = P_{A} + P_{B} + P_{C} + . . . = \sum_{i} P_{i}

P_{A} = X_{A} P_{T}

X_{A} = \frac{n_{A}}{n_{T}}

r a t e o f d i f f u s i o n = \frac{a m o u n t o f g a s p a s s i n g t h r o u g h a n a r e a}{u n i t o f t i m e}

\frac{r a t e o f e f f u s i o n o f A}{r a t e o f e f f u s i o n o f B} = \frac{\sqrt{m_{B}}}{\sqrt{m_{A}}} = \frac{\sqrt{M_{B}}}{{\sqrt{M}}_{A}}

u_{r m s} = \sqrt{\overset{―}{u^{2}}} = \sqrt{\frac{u_{1}^{2} + u_{2}^{2} + u_{3}^{2} + u_{4}^{2} + . . .}{n}}

K E_{a v g} = \frac{3}{2} R T

u_{r m s} = \sqrt{\frac{3 R T}{M}}

Z = \frac{m o l a r v o l u m e o f g a s a t s a m e T a n d P}{m o l a r v o l u m e o f i d e a l g a s a t s a m e T a n d P} = {(\frac{P V_{m}}{R T})}_{m e a s u r e d}

(P + \frac{n^{2} a}{V^{2}}) (V - n b) = n R T
