water is made of two elements oxygen and hydrogen. H2O..being that there are two parts of hydrogen and one part oxygen. then most of the mass of water would be hydrogen.

Which elements make up the most common compound in the human body?
Hydrogen and oxygen Water is the most common molecule, between 55 and 65% of our mass. Hydrogen accounts for 63% of our atoms, but oxygen accounts for 65% of our mass. (Both hydrogen and oxygen are part of many other molecules besides water.)

How much of the world is made of water?
Water accounts for about 1/50 th or 2% of the earths mass.
What part of the solar system accounts for 995 of the mass of the solar system?
I am not sure about the percentage, but most of the mass is concentrated in the Sun.
How much hydrogen is in the human body?
Most of the hydrogen in our body floats around in the form of water. The human body is about 60% water and hydrogen only accounts for 11% of that water mass. Thus, roughly 6.6% of a typical human's body mass is hydrogen.
How does water reach the atmosphere and tell which way accounts for most of the water in the atmosphere?
Evaporation.
Where is the great majority of the mass of the atom found?
Most of the mass of an atom is found in its nucleus.
What cell has the most mass?
Water :)
An air mass that forms over water at high latitude is most likely?
An air mass that forms over water at high latitude is most likely cold. The air mass over the water would also be quite humid.
What did Jan Van Helmont concluded that plants get most of their mass from?
Van Helmont concluded that most of the mass the plant gained had come from water.
How can that the body has 10 percent hydrogen and 63 percent of the atoms are hydrogen?
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.
