Question

If 8.0g of H2 reacts and 72g of H2O is produced how much O2 is consumed in the reaction

Answer 1

64 g of O₂ is consumed in this reaction.

Step-by-step explanation:

Mass of H₂O = 72 g

Mass of H₂ = 8 g

So, mass of O₂ consumed = mass of H₂O - mass of H₂ = 72 - 8 = 64 g

64 g of O₂ is consumed in this reaction.
