What is the volume (in litres) of oxygen at STP required for complete combustion of 32 ~g of CH ₄ ? (Molecular weight of CH ₄ is 16 )

Options

  1. A44.8
  2. B89.6
  3. C22.4
  4. D179.2

Correct answer

B. 89.6

Step-by-step solution

16 ~g CH ₄ + 2 22.4 ~L 2 O ₂ CO ₂+2 H ₂ O Volume of required for 16 ~g ₄ is =2 22.4 ~L Volume of O ₂ required for 32 ~g CH ₄ is = 2 22.4 16 32=89.6 ~L
