H is the chemical formula for hydrogen. There are some elements with H in the chemical formula. But the have other letters too.
By looking at an actual chemical formula for a compound, we could tell you how many hydrogen atoms there are per molecule (or at least per formula unit) of that compound.Without the specific chemical formula, we can't. So the question is meaningless ... how many hydrogen atoms are present in a chemical formula depends on what the chemical formula is.
The number of hydrogen atoms of present in a hydrogen molecule are 2.
The chemical formula for hydrogen peroxide is H2O2, that is, two parts oxygen for every two parts hydrogen.
The chemical formula of adrenaline is C19H13NO3 - the number of hydrogen atoms is 13.
Carbon:4 Hydrogen: 8 Oxygen:4 overall: 16 There would be 8 if there was not a 2 in front of the formula.
There are 12 hydrogen atoms is C6H12O6 (glucose).
The chemical formula is NH31+ so there are 3 hydrogen atoms but one of the hydrogen atoms is missing its electron.
The chemical formula of adrenaline is C19H13NO3 - the number of hydrogen atoms is 13.
There are four elements in the chemical formula NaCOHCl: Sodium (Na), Carbon (C), Oxygen (O), Hydrogen (H), and Chlorine (Cl).
The chemical formula of water is H2O; water contain two hydrogen atoms.
The hydrogen phosphide (syn.: phosphine, phosphane) has the chemical formula PH3.
