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).

What elements make up water?
Water contains the elements hydrogen and oxygen in a 2 to 1 ratio. The chemical formula for water is H2O.
Give reason water is a compound and not a mixture?
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
Why are elements and compounds are pure substances and homogeneous mixture are not?
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.
What is a substance formed from two or more elements form when chemically combined in a set ratio?
A compound is a chemical combination of two or more elements in a fixed ratio.
What is the ratio of the main elements in nucleic acids?
i like men

What are composed elements combined in a specific ratio called?
what consists of elements combined in a specific ratio?
Shows the ratio of elements in a compound?
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.
What is the ratio of the elements in the compound KI?
The elements present in KI are potassium (K) ad iodine (I). These elements are present in the ratio 1:1
Why are elements and compounds pure substances while a homogeneous mixture is not?

A notion that shows what elements a compound contains and the ratio of the atoms or ions of these elements in the compound?
A chemical formula shows what elements a compound contains, and the ratio of the atoms or ions of the elements in the compound.
What is the ratio of sulphur?
The ratio of sulphur to all other elements, in the universe, is 0.
Is metal alloys a mixture?
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.
What is the fixed ratio of a chemical compound called?
The fixed ratio of the elements in a chemical compound is called its RATIO OF MASSES.
What two elements are present in all water?
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.
