So, in a spoon of water, if you have $$1 \, \mathrm{gm}$$ of Hydrogen, you will always have $$8 \, \mathrm{gm}$$ of Oxygen. If you took $$58 \, \mathrm{gm}$$ of salt, you will find that it has $$23 \, \mathrm{gm}$$ of Sodium and $$35 \, \mathrm{gm}$$ of Chlorine.
Can we split $$9 \, \mathrm{gm}$$ of water to get $$2 \, \mathrm{gm}$$ of Hydrogen and $$7 \, \mathrm{gm}$$ of Oxygen?
