A gaseous mixture containing $\mathrm{H}\mathrm{e},\mathrm{ }\mathrm{C}{\mathrm{H}}_4$ and $\mathrm{S}{\mathrm{O}}_2$ was allowed to effuse through a fine hole then find what molar ratio of gases coming out initially? (Given mixture contains $\mathrm{H}\mathrm{e},\mathrm{C}{\mathrm{H}}_4$ and $\mathrm{S}{\mathrm{O}}_2$ in 1 : 2 : 3 mole ratio)

• A

  $\sqrt{2}:\sqrt{2}:3$
• B

  $2:2:3$
• Correct answer
  C

  $4:4:3$
• D

  $1:1:3$

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