This observation led scientists to come up with another law, the

So, in a spoon of water, if you have \(1 \, \mathrm{gm}\) of Hydrogen, you will

**Law of Constant Proportions**. It states that*in a chemical substance, the elements are always present in definite proportion by mass*.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?
