Yes, of course: Two thirds of all the atoms (although only a much smaller fraction of the mass) of water are hydrogen atoms.
99 percent of the human body contains carbon, oxygen and hydrogen atoms. The composition of hydrogen in human body is 9.5 percent.
Hydrogen in sulphuric acid: approx. 2%.
Citric Acid
If you mean hydrogen in elemental form, it's darn near zero.
According to Education.com, the hydrosphere is made of oxygen at 86 percent, hydrogen at 11 percent and other elements totalling 3 percent.
The elements that are in Earths Hydrosphere is Oxygen with 33.0% of volume, Hydrogen with 66.0% of volume, and 1.0% of unknown elements.

I believe it is Hydrogen
3% of the hydrosphere is freshwater, while 97% of it is saltwater.
The hydrosphere is made up of a variety of gases including oxygen, hydrogen, and carbon dioxide. The hydrosphere includes water in several forms including in gaseous states.
97 % salt, 3 % fresh.
False, ocean water makes up 93% of the hydrosphere. Fresh water makes up 7% of the hydrosphere. The hydrosphere takes up 75% percent of the earth's surface.
Yes, of course: Two thirds of all the atoms (although only a much smaller fraction of the mass) of water are hydrogen atoms.
