The volume of oxygen required for complete combustion of 0.25 mole of methane at S.T.P. is

Options

  1. A5 6 dm ³
  2. B7 46 dm ³
  3. C22 4 dm ³
  4. D11 2 dm ³

Correct answer

D. 11 2 dm ³

Step-by-step solution

(C) CH ₄+2 O ₂ CO ₂+2 H ₂ O 1 mole of methane required =2 22.4 dm ³ of O ₂ 0.25 mole of methane required =2 22.4 0.25=11.2 dm ³ of O ₂
