Answer:

9moles of hydrogen gas

Explanation:

To solve this problem, we write the reaction expression first;

                       2H₂   +   O₂    →     2H₂O

We have been given the number of moles of oxygen gas to be:

 Number of moles of oxygen gas  = 4.5moles

From the balanced reaction expression:

      1 mole of oxygen gas reacts with 2 moles of hydrogen gas

  4.5moles of oxygen gas will react with 4.5 x 2  = 9moles of hydrogen gas
