Answer:
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.
