Suppose you had 20 moles of H2 on hand and plenty of O2m how many moles of H2O could you make?
2 H2 + O2 ------> 2 H2O

20 moles.
the amount of molocules would be the same, but they'd be bigger

20, The solution is similar to your other question.
Remember 1 mole just means 6.022 x 10^23 number of anything (atoms, molecules, horses, cars, etc...)
Since you are looking for a number of moles of one substance based on a number of moles of another substance, just look at the chemical equation and balance out the ratios.
In the equation : 2 H2 + O2 => 2 H2O
You know that 2 H2 molecules will make 2 H2O molecules. The ratio will work the same for moles. So 2 moles of H2 will make 2 moles of H2O
Likewise 1 O2 molecule will make 2 H2O molecules, again the ratio will be the same. So 1 mole of O2 will make 2 moles of H2O
Therefore:
20 moles of H2 will make 20 moles of H2O.
I hope that helps!

because the ratio of H to O is 2 to 1
20 H will need 10 O
So you will make 10 moles of water
