Question

C3H8+5O2--------3CO2+4H20 How many moles of water will be produced by the complete combustion of 0.5 moles of propane C3H8?

Answer 1

2 moles

Step-by-step 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.
