Answer:
3 moles
Explanation:
This question is on stoichiometry of reactions
Given
2H₂ +O₂⇒2H₂O-------------------the equation is balanced
Find the mole ratio
2H₂ +O₂⇒2H₂O
2 1 2
O:H = 2:1---------------------------------every mole of hydrogen requires two moles of oxygen to complety react
Thus given 6 moles of hydrogen;
O:H
?:6
=6/2=3 moles
