NEET Chemistry States Of Matter MCQs

Choose the correct option for the total pressure (in atm.) in a mixture of 4 g ${O_2}$ and 2 g ${H_2}$ confined in a total volume of one litre at ${0^0}C$ is[Given $R = 0.082{\rm{L}}\,\,{\rm{atm}}\,\,{\rm{mo}}{{\rm{l}}^{ - 1}}\,{K^{ - 1}},\,T = 273{\rm{K}}$]

A mixture of ${{\rm{N}}_{\rm{2}}}$ and ${\rm{Ar}}$ gases in a cylinder contains ${\rm{7 g}}$of ${{\rm{N}}_{\rm{2}}}$ and ${\rm{8 g}}$ of ${\rm{Ar}}$. If the total pressure of the mixture of the gases in the cylinder is ${\rm{27}}$ bar, the partial pressure of ${{\rm{N}}_{\rm{2}}}$ is :
