Choose the correct option for the total pressure (in atm.) in a mixture of $4\mathrm{g} {\mathrm{O}}_2$ and $2\mathrm{g} {\mathrm{H}}_2$ confined in a total volume of one litre at $0°\mathrm{C}$ is

[Given $\mathrm{R}=0.082 \mathrm{L} \mathrm{atm} {\mathrm{mol}}^{-1}{\mathrm{K}}^{-1}, \mathrm{T}=273 \mathrm{K}$]

• A

  $2.518$
• B

  $2.602$
• Correct answer
  C

  $25.18$
• D

  $26.02$

Hence, the correct answer is option: 'C'.
