Determining Moles of Oxygen Needed in a Reaction

Very Easy General Chemistry Stoichiometry And Chemical Reactions

Consider the following balanced chemical equation:

2H₂ + O₂ → 2H₂O

This equation indicates that two moles of hydrogen gas react with one mole of oxygen gas to produce two moles of water. Based on this information, how many moles of oxygen are needed to react completely with six moles of hydrogen gas?

1 mole

2 moles

3 moles

4 moles
