Scientists observed that if you split $$9 \, \mathrm{gm}$$ of Water, you get $$1 \, \mathrm{gm}$$ of Hydrogen and $$8 \, \mathrm{gm}$$ of Oxygen. Even when the experiment was conducted thousands of times, the result was the same.
If you split $$18 \, \mathrm{gm}$$ of Water, what do you get?
• $$1 \, \mathrm{gm}$$ of Hydrogen and $$17 \, \mathrm{gm}$$ of Oxygen
• $$1 \, \mathrm{gm}$$ of Hydrogen and $$8 \, \mathrm{gm}$$ of Oxygen
• $$2 \, \mathrm{gm}$$ of Hydrogen and $$16 \, \mathrm{gm}$$ of Oxygen
• $$10 \, \mathrm{gm}$$ of Hydrogen and $$8 \, \mathrm{gm}$$ of Oxygen
