The total number of moles Remain corratants

\mathrm{n_{1}+n_{2}+n_{3}=n f}

\mathrm{n_{1},n_{2},n_{3}} moles at gases in the individual containers, nf is the resultant mole.

Using ideal gas equations \mathrm{P_{v}=nRT}

\mathrm{\frac{P_{1} v_{1}}{R_{T}}+\frac{P_{2} v_{2}}{R_{T}}+\frac{P_{3} v_{3}}{R_{T}} =\frac{P_{f} V_{f}}{R_{T}}}
\mathrm{P_{1} v_{1}+P_{2} v_{2}+P_{3} v_{3} =P f V_{f}}
\mathrm{1 \times 4+2 \times 5+3 \times 7 =P f \times 16}

\mathrm{P_{f} =\frac{4+10+21}{16}=9.18 \mathrm{Atm}}
