It depends on how much water you have!
2 atoms of hydrogen for every atom of oxygen.
No, the chemical formula for water is H2O. This means that for every oxygen atom in the compound, there are two hydrogen atoms. Thus, the number of hydrogen atoms in water is double the number of oxygen atoms.
Many, many compounds contain either hydrogen atoms, oxygen atoms, or both. Far too many to list here, in fact.Most prominently water and hydrogen peroxide both contain nothing but oxygen and hydrogen atoms.
There are three atoms in a molecule of water. One oxygen atom and 2 hydrogen atoms. The simplified form for the molecule of water is H2O which is a coded form for the 2 hydrogen and 1 oxygen atoms that make up the molecule.
water
Water is compound that has 2 hydrogen atoms and 1 oxygen atom: H2O.
In one molecule of water there are 3 atoms. One oxygen atom and two hydrogen atoms.
A water molecule is composed of two hydrogen atoms and one oxygen atom. The formula is H2O.
There are two types of elements in water. It is made up of Oxygen and Hydrogen. There are two Hydrogen atoms for every Oxygen atoms and the chemical compound of water is H2O.
3 Two hydrogen atoms and one oxygen atom.
Water has a higher percentage of hydrogen by mass than does hydrogen peroxide, because the latter has equal numbers of hydrogen and oxygen atoms while the former has twice as many hydrogen atoms as oxygen atoms.
the water molecule is H2O so it has 2 atoms of hydrogen in it. (plus an atom of oxygen)
