Zero. The formula for hydrogen chloride gas is HCl. It does not contain oxygen.
Hydrogen peroxide has two atoms of hydrogen and oxygen.
Common table salt is Sodium Chloride ( NaCl ) and has no hydrogen 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.
3 Hydrogen and 2 Oxygen
A total of two hydrogen atoms can bond to a single oxygen atom.
The number of hydrogen atoms is twice the number of oxygen atoms. Glucose is C6H12O6, so there are 12 hydrogen atoms for every 6 oxygen atoms in a molecule.
Oxygen atoms weigh more than Hydrogen atoms.
2 atoms of hydrogen for every atom of oxygen.
2x2= 4 hydrogen atoms (2x1= 2 oxygen atoms).
There are 22 atoms of hydrogen, 12 atoms of carbon, and 11 atoms of oxygen.
There is 1 hydrogen atom and 1 chlorine atom in Hydrogen Chloride.
There are twice as many hydrogen atoms as oxygen atoms in a polysaccharide. The general formula for this is Cx(H2O)y.
