Answer:

1.5 moles

Explanation:

Given data:

Number of moles of O₂ consumed = 2.5 mol

Moles of CO₂ produced = ?

Solution:

Chemical equation:

C₃H₈ + 5O₂    →     3CO₂ + 4H₂O

Now we will compare the moles of oxygen with carbon dioxide from balance chemical equation:

                             O₂             :           CO₂

                               5             :            3

                              2.5           :         3/5×2.5 = 1.5

Thus from 2.5 moles of oxygen 1.5 moles of carbon dioxide are produced.
