How many moles of hydrogen are required to make 32 moles of water?
You multiply 32 by 2, since there are two hydrogens in every water molecule.
We know that there are 2 moles of H in 1 mole of water. How many moles of H are there in 32 moles of water?
H2O ----------------- H
1 mol --------------- 2 mols
32 mol ------------- x
1 . X = 32. 2 ⇒
X = 64 mols of H
Answer:
\(\boxed{\boxed{64\: mols\: of\: Hydrogen}}\)
