Answer: Molecules do not necessarily have any hydrogen atoms (e.g. NaCl has only sodium and chlorine and no hydrogen)
The lowest number of hydrogens possibly present is one. This occurs in compounds like hydrogen chloride (HCl).
Many molecules have two hydrogens, the simplest is hydrogen gas (H2)
After this it's open season on hydrogens. Complex hydrocarbons (for example, polyethylene and heavy alkane oils) can have several hundred carbons each with two hydrogens and two extra to cap the ends (general formula : CnHn+2)

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 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 hydrogen atoms are in one molecule of sugar?
That depends on what kind of sugar you're talking about. Table sugar, or sucrose, has the formula C12H22O11. One molecule of sucrose has 22 hydrogen atoms. Blood sugar, or glucose, has the formula C6H12O6. One molecule of glucose has 12 hydrogen atoms. Other types of sugar have different formulas. If you know the chemical formula, look at the subscript to the right of the H to see how many hydrogen atoms are in one molecule of sugar.
How many numbers and type of atoms are present in hydrogen sulfide?
Each molecule of hydrogen sulfide contains two hydrogen atoms and one sulfur atom.
How does molecule differ from an atom?
A molecule may be one or more atoms, where as an atom can only be one atom. For instance there are hydrogen atoms, and diatomic hydrogen molecules.
How many atoms of hydrogen does one molecule ofvwater have?
2 hydrogen atoms.
How many hydrogen atoms does a single molecule of methane contain?
The hydrogen molecule contains 4 Hydrogen atoms, and one Carbon in the centre.
How many atoms are there of hydrogen in water?
H2OCount two atoms hydrogen in one molecule of water.
How many hydrogen atoms in one molecule of caffeine?
Caffeine is C8H10N4O2 and has 10 hydrogen atoms.
Why one mole of hydrogen molecule and one mole of hydrogen atoms have different masses?
because there are 2 hydrogen atoms in the molecule of hydrogen atoms
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 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 a molecule of hydrogen oxcide?
Hydrogen oxide (also known as water) contains two hydrogen atoms and one oxygen atom in each molecule.
How many hydrogen atoms is there in one water molecule?
two
What atoms and how many of each are found in a molecule of water?
In one Molecule of water there are two hydrogen atoms and one oxygen atom
How many atom does hydrogen have?
One molecule of hydrogen gas contains two hydrogen atoms.
How is a molecule of hydrogen form from two hydrogen atoms?
Well with any element when two atoms are put together they are known as a molecule of that element. So one atom of hydrogen is known as one atom of hydrogen and two atoms of hydrogen is known as one molecule of hydrogen.
