# If 100 molecules of oxygen react, how many molecules of water will be produced?

Jul 18, 2018

Would not 200 molecules of water be produced...?

#### Explanation:

We examine the stoichiometric equation to establish the stoichiometric equivalence...

${H}_{2} \left(g\right) + \frac{1}{2} {O}_{2} \left(g\right) \rightarrow {H}_{2} O \left(l\right)$..

...and thus EACH equiv of dioxygen gas gives TWO equiv of water. Since you specify 100 molecules of dioxygen...200 molecules of water thus result... Agreed?
