To find out how many moles of H2O are produced from 22.5 mol of O2, you can use the concept of mole ratio from the balanced chemical equation.
From the equation 2H2 + O2 -> 2H2O, you can see that 1 mole of O2 reacts to produce 2 moles of H2O.
Using this information, we can set up a ratio:
1 mol O2 : 2 mol H2O
Now, we want to find how many moles of H2O are produced from 22.5 mol of O2, so we can set up a proportion:
(22.5 mol O2) / (1 mol O2) = (x mol H2O) / (2 mol H2O)
Cross-multiplying, we have:
22.5 mol O2 * 2 mol H2O = x mol H2O * 1 mol O2
45 mol H2O = x mol H2O
Therefore, 22.5 mol of O2 will produce 45 mol of H2O.
So in your calculation, the result should be:
22.5 mol O2 * 2 mol H2O / 1 mol O2 = 45 mol H2O
