What volume of oxygen gas ( O ₂ ) measured at 0^ C and 1 atm, is needed to burn completely 1 ~L of propane gas ( C ₃ H ₈ ) measured under the same conditions?

Options

  1. A10 ~L
  2. B7 ~L
  3. C6 ~L
  4. D5 ~L

Correct answer

D. 5 ~L

Step-by-step solution

aligned & 22.4 ~L at STP C ₃ H ₈( ~g ) + 5 22.4 ~L at STP 5 O ₂( ~g ) 3 CO ₂( ~g )+4 H ₂ O ( I ) & 22.4 ~L C ₃ H ₈ at STP 5 22.4 ~L of O ₂ at STP & 1 LC ₃ H ₈ at STP 5 22.4 22.4 of O ₂ at STP & =5 ~L of O ₂ at NTP & aligned
