The answer depends on the context. Hydrogen is the most abundant element (by mass) in the universe while oxygen is the most abundant in the earth's crust. The ratio of hydrogen to oxygen, in the universe is 75:1 whereas for the earth's crust it is 7:2305 (= approx 0.00304).
It depends on the water sample. Different sources of water have different constituents. Those constituents can change on a daily basis even for normal, domestic, city tap water
Water contains the elements hydrogen and oxygen in a 2 to 1 ratio. The chemical formula for water is H2O.
A compound is defined by a substance in which the elements that it is made of are in a fixed ratio. In this case the ratio between the hydrogen and oxygen in 2:1. A mixture is a substance in which the elements that make it are not in a fixed ratio
Well, elements and compounds are pure substances. This is because the atoms in an elements are of one type only. Thus making it pure. But in a compound, the ratio of the masses of the combining elements or compounds are fixed. For example, the ratio for hydrogen and oxygen to combine together to form water is 1:8. Therefore the compound is also a pure substance. But homogenous mixtures are not pure substances as the components can be mixed in any ratio. We can make brine solution by mixing any amount of salt and water. There is no fixed ratio. So homogenous mixtures are not pure.
A compound is a chemical combination of two or more elements in a fixed ratio.

what consists of elements combined in a specific ratio?
The chemical formula of the compound shows the ratio of the atoms of elements in a compound. This must not be confused with the ratio of their masses.
The elements present in KI are potassium (K) ad iodine (I). These elements are present in the ratio 1:1

A chemical formula shows what elements a compound contains, and the ratio of the atoms or ions of the elements in the compound.
The ratio of sulphur to all other elements, in the universe, is 0.
An alloy is a mixture of Metals. A mixture is a combination of elements in an unfixed ratio. A compound is a mixture of elements in a fixed ratio.
The fixed ratio of the elements in a chemical compound is called its RATIO OF MASSES.
Hydrogen and Oxygen Recall that water is H2O. So the two elements are H (hydrogen) and O (oxygen) and they are in a 2 to 1 ratio, as determined by the molecular formula (H2O). So, hydrogen and oxygen.
