Question

How much volume of co2 at STP is liberated by the combustion of hundred cm cube of propane

Answer 1

C₃H₈ + 5O₂ ⇒ 3CO₂ + 4H₂O

Given,

100 cm³ of C₃H₈

Now,

1 mole ie 22.4L of C₃H₈ will produce 3 moles ie (22.4 * 3)L

1L C₃H₈ will produce (3*22.4/22.4)L CO₂

Therefore, 100 cm³ will produce 0.3L of CO₂
