Problem

298\,\text{K}

, a sealed

5.0\,\text{L}

container holds a mixture of

\mathrm{H_2}

\mathrm{CH_4}

, and

\mathrm{CO_2}

with a total pressure of

760\,\text{torr}

. The partial pressure of

\mathrm{CO_2}

95\,\text{torr}

, and the partial pressure of

\mathrm{CH_4}

is twice that of

\mathrm{H_2}

. Determine the mole fraction of each gas in the mixture.
