Exam the ideal gas equation,
\mathrm{P=\frac{n R T}{V} \quad P =\text { pressure of oxygen } }
                         \mathrm{V =\text { volume of oxygen } }
                         \mathrm{T =\text { Temperature of oxygen in } k }
                          \mathrm{n =\text { Number of Moles of oxygen } }

\mathrm{n=\frac{32}{32}=1 }
\mathrm{p=\frac{1 \times 0831 \times 300}{5} }

\mathrm{p=4.986 \, \mathrm{bar} }
