If you are asking how many atoms of Hydrogen are in that molecule, the answer is 5, hence the "H5".
If you are asking how many molecules are needed in the reaction that results in C3H5, it could be 5 or more depending on the molecules and energies involved.
Just count up the number of hydrogen atoms in the formula, H5 plus the H at the end, and the answer is 6 hydrogen atoms are required.
The chemical formula represents 6 hydrogen atoms.
There are 6 atoms

it is unknown the number of hydrogen atoms in a fat molecule but there is still hope that someone knows. if you have a assignment dont worry because someone will know

2 hydrogen and 1 oxygen particle the molecular mass is 10 that is the number of protons in the molecule.
The number of hydrogen atoms of present in a hydrogen molecule are 2.
Hydrogen exist as H2.It has 2 atoms in a molecule.

saturated molecule
Hydrogen chloride molecule (HCl) has two atoms.
Molecular hydrogen that occurs naturally is H2 which has 2 atoms per molecule.
The chemical formula of ethyne (acerylene) is C2H2 - two hydrogen atoms.
The molar mass of hydrogen is 2.
The number of neutrons will vary depending on the isotopes of hydrogen and oxygen in the molecule. The number of protons and electrons will be 10 each in every molecule.
by checking its number of hydrogen atoms
Water H= Hydrogen O=Oxygen 2=is the number of Hydrogen molecules for each Oxygen molecule.
the smallest atom is hydrogen, the smallest molecule would be the naturally occurring diatomic hydrogen.
