A $1\mathrm{.}00L$ mixture of helium, neon, and argon has a total pressure of $662mmHg$ at $298K.$ If the partial pressure of helium is $341mmHg$ and the partial pressure of neon is $112mmHg,$ What mass of argon is present in the mixture?

A $12\mathrm{.}5$ L scuba diving tank contains a helium$-$oxygen $($heliox$)$ mixture made up of $24\mathrm{.}21g$ of $He$ and $4\mathrm{.}32g$ of $02$ at $298$ K$.$ Calculate the mole fraction and partial pressure of each component in the mixture and the total pressure of the mixture.

xit Slip: A diver breathes a heliox mixture with an oxygen mole fraction of $0\mathrm{.}050.$ What must the total pressure be for he partial pressure of oxygen to be $0\mathrm{.}21$atm $?$
