Taking into account the reaction stoichiometry, 36 grams of water (option B) will be produced if you start with 4.0 grams of hydrogen and an excess of oxygen.

Reaction stoichiometry

In first place, the balanced reaction is:

2 H₂+ O₂  → 2 H₂O

By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:

  • H₂: 2 moles
  • O₂: 1 mole
  • H₂O: 2 moles

The molar mass of the compounds is:

  • H₂: 2 g/mole
  • O₂: 32 g/mole
  • H₂O: 18 g/mole

Then, by reaction stoichiometry, the following mass quantities of each compound participate in the reaction:

  • H₂: 2 mole× 2 g/mole= 4 grams
  • O₂: 1 mole× 32 g/mole= 32 grams
  • H₂O: 2 moles× 18 g/mole= 36 grams

Mass of H₂O formed

You can see that by reaction stoichiometry 4 grams of H₂ form 36 grams of H₂O.

Summary

In summary, 36 grams of water (option B) will be produced if you start with 4.0 grams of hydrogen and an excess of oxygen.
