Problem

A container holds a mixture of two ideal gases in thermal equilibrium. Species A has mass

m_{A}

and number density

n_{A}

; species B has mass

m_{B}

and number density

n_{B}

. Both species share the same mean square speed

\langle v^{2}\rangle

. (a) Write an expression for the total pressure

P_{\text{tot}}

on one wall in terms of

n_{A},\,n_{B},\,m_{A},\,m_{B},

and

\langle v^{2}\rangle

. (b) Determine the fraction of

P_{\text{tot}}

that is contributed by species B.
