Answer: 1.5 moles O2
Explanation:
The number of moles of each reactant and product is the number in front to the molecule when the equation is balanced.
You know that 1 mole of O2 gives you 2 moles of H2O
So you can set up a proportion using that.
1 mole O2. X moles O2
-------------- = -------------------
2 moles H2O. 3 moles H2O
Then cross multiply
2x=3
X=3/2 Or 1.5
So you need 1.5 moles O2 to get 3 moles of H2O.
