sorry dude,
The chemical equation for reacting hydrogen and oxygen is:
2H²+O² −>2H²O²
We can interpret this as 2 moles of hydrogen gas reacts with 1 mole of oxygen gas to form 2 moles of water.
In your question you are burning 10 grams of H², so this is 5 moles H². And this results in 5 moles of H²O.
The molar mass of water is 18, so 5*18 = 90 grams of water.
