10 moles of H2 reacts with 5 moles of O2 creating 10 moles of water.
Water has the molar mass 18 g/mole
10 · 18g = 180 g
180 g of water can be produced from 10 moles of hydrogen gas.

- Fossil fuel may be present in solid, liquid as well as in gaseous form so the given option (a) is incorrect.
- This is the wrong assumption that in the fossil fuel we get the fossils of dinosaur, so option (c) is incorrect.
