Answer:
1.4moles
Explanation:
From the balanced equation below;
2H2 + O2 → 2H2O
2moles of hydrogen reacts with 1mole of oxygen to produce 2moles of water.
since we are only interested in comparing hydrogen and water, we can say 2moles of hydrogen will produce 2moles of water
Hence by comparism of moles;
1.4moles of hydrogen will produce 1.4moles of water
