C3H8+5O23CO2+4H20 How many moles of water will be produced by the complete combustion of 0.5 moles of propane C3H8?

2 moles

Explanation:

Given data:

Moles of water produced =?

Moles of propane = 0.5 mol

Solution:

Chemical equation:

C₃H₈ + 5O₂ → 3CO₂ + 4H₂O

Now we will compare the moles of propane and C₃H₈.

                C₃H₈         :          H₂O  

                   1             :             4

                  0.5         :           4/1×0.5 = 2 mol

Thus 2 mole of water are produced from 0.5 moles of propane.
