Does the 2 mean How many hydrogen atoms are in a molecule of water?

Yes. In the chemical formula H2O, the subscript 2 after the hydrogen means there are two hydrogen atoms in a molecule of water. The absence of a subscript after the oxygen means the subscript is understood to be 1, so there is one atom of oxygen in a water molecule.

How many atoms are there in a molecule os water?
In one molecule of water there are 3 atoms. One oxygen atom and two hydrogen atoms.
How many atoms of hydrogen are in a molecule of hydrogen oxide?
hydrogen oxide is water or H2O and has two hydrogens
How many hydrogens are In one molecule of water?
The chemical formula for water is H2O. The subscripted "2" indicates that there are two atoms of hydrogen in one water molecule. No subcripted number means there is just one atom in the molecule, meaning there are two hydrogen atoms and one oxygen atom.
How many atoms makes up each water molecule?
6 : 4 hydrogen 2 oxygen ------------------------------------ That would be for two water molecules as one is H20 - therefore 3 atoms
How many hydrogen atoms would it take to make a stable compound with oxygen?
For the water molecule (H2O) two hydrogen atoms are needed.
How many hydrogen atoms are present in a water molecule?
there are 2 atoms of hydrogen in water
How many hydrogen atoms in water?
2 hydrogen atoms per molecule of water.
How many atoms are there of hydrogen in water?
H2OCount two atoms hydrogen in one molecule of water.
How many atoms does water make up?
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.
How many atoms of hydrogen are in water molecule?
the water molecule is H2O so it has 2 atoms of hydrogen in it. (plus an atom of oxygen)
How many atoms are there in a molecule os water?
In one molecule of water there are 3 atoms. One oxygen atom and two hydrogen atoms.
How many molecules of hydrogen in water?
There are two atoms of hydrogen in a water molecule, but no hydrogen molecules.
How many hydrogen atoms are in a representative particle of water?
A water molecule (H2O) contain two hydrogen atoms.
How many hydrogen atoms atoms are present in each water molecule?
There are 2 hydrogen atoms present in each water molecule. This can be seen from the formula for water H2O -- this tells us there are 2 atoms of hydrogen combined with 1 atom of oxygen
How many molecules are present in a molecule of hydrogen?
there are 2 atoms of hydrogen in water
How many hydrogen atom are present in each molecule?
Per every water molecule, there are 2 hydrogen atoms and 1 oxygen atom. These atoms make up a water molecule.
How many hydrogen atoms are in each molecule of water?
H20, so that would be two hydrogen atoms.
