When 22.4 ~L of C ₄ H ₈ at STP is burnt completely, 89.6 ~L of CO ₂ gas at STP and 72 g of water are produced. The volume of the oxygen gas at STP consumed in the reaction is closest to :

Options

  1. A89.6 L
  2. B112 ~L
  3. C134.4 ~L
  4. D22.4 L

Correct answer

C. 134.4 ~L

Step-by-step solution

For complete combustion of 1 mole C ₄ H ₈ 6 mole O ₂ required array l n _ o ₂ =6 mole V _ o ₂ =6 22.4 ~V _ o ₂ =134.4 lit. array
