Answer:

Propane burns in air according to the following equation:

C

O.

1 mole of propane combines with 5 moles of oxygen.

Volume is directly proportional to the number of moles.

1 cm

Reaction

C₃H₈ + 5O₂ → 3CO₂ + 4H₂O

Avogadro: at the same T and P, the ratio of gas volume = the ratio of gas moles  

volume of CO₂ = 3/1 x 25 = 75 m³
