What volume of water vapor will be produced from the reaction of 24.65 l of oxygen?

49.30 L

Explanation:

1. Write the chemical equation.

You don’t give the reaction. However, if all the H₂O comes from O₂, we can write a partial equation. The important point is that we must balance the O atoms.

       O₂ + … ⟶ 2H₂O + …

V/L:  1 L                2 L

2. Calculate the volume of N₂.

We can use Gay-Lussac's Law of Combining Volumes to solve this problem.

According to the law, 1 L of O₂ produces 2 L of H₂O.

Then, the conversion factor is (2L H₂O/1 L O₂).

Volume of H₂O = 24.65 × 2/1

Volume of H₂O = 49.30 L
