Answer:

32 mols of water

Explanation:

2H2 + O2 ==> 2H2O

What your givens are telling you and what the equation is saying is that

for every mol of O2, you get 2 mols of H2O

So you could do it with the proportion about.

1/16 = 2/x                 Cross multiply

x = 16 * 2

x = 32

Answer:

32 mol

Explanation:

The balanced reaction from Oxygen and Hydrogen to form Water is:

(1/2)O₂ + H₂ ⇒ H₂O

So, 1/2 mol of oxygen forms 1 mol of water. The stoichiometry calculus must be:

1/2 mol of O₂ -------------------------- 1 mol of H₂O

16 mol of O₂ --------------------------- x mol of H₂O

By a direct simple three rule:

(1/2)x = 16

x = 32 mol
