Hydrogen is the lightest of all elements, having atoms that are only a fraction of the mass of all other elements. For example, an oxygen atom has about 16 times the mass of a hydrogen atom. So while a water molecule contains 2 hydrogen atoms and 1 oxygen atom (and water makes up most of the human body), the single oxygen atom accounts for most of the mass of the molecule.
To answer your question on how many hydrogen atoms are there in caffeine, the scientific answer would be 10 atoms of hydrogen.
Decane has 10 carbon atoms and 22 hydrogen atoms.
Caffeine is C8H10N4O2 and has 10 hydrogen atoms.
The human body is about 70% water which is H2O, so most of the atoms are hydrogen. But hydrogen atoms are very light, so by weight, most of the atoms are oxygen. By weight, the human body is 65% oxygen, 18% carbon, 10% hydrogen, 3% nitrogen, 1.5% calcium and 1.2% phosphorus. Those 6 elements account for over 98% of all the atoms in a human body.

There is a total of 3 hydrogen atoms in a molecule of vinegar.
One molecule of C6H10O5 contains 10 atoms of hydrogen
there are a total of 10 atoms in ribose
Chemical formula for water is H2O. One water molecule has 2 hydrogen atoms. That means 10 hydrogen atoms are needed to form five water molecules.The ration between hydrogen and oxygen in a water molecule is 2:1. In five water molecules, there are five oxygen atoms. According the ratio, there are 10 hydrogen atoms.
Hydrogen accounts for 10 percent mass in the human body. It is important in energy production and the H plus ions are used to regulate chemical reactions and produce ATP.
It has 10 carbon atoms, 20 hydrogen atoms, and 1 oxygen atoms. C10H20O1
