In the box provided explain why living organisms contain more hydrogen atoms than any other atoms, yet 65% of a typical organism’s mass is oxygen

iving organisms contain more hydrogen atoms than any other atoms, yet 65% of a typical organism’s mass is oxygen because Oxygen atoms contain 16 times more mass than the mass of hydrogen atoms.

The atomic mass of oxygen is 16 while that of Hydrogen is 1.

Further Explanation:Oxygen  Oxygen is an element in the periodic table that exists as a diatomic molecule.Oxygen is a gas found in the atmosphere, about 21% of the air in the atmosphere.Oxygen has an atomic mass of 16, such that an atom of oxygen has a mass of 16.Oxygen is the most abundant element by mass in living organisms, about 65% of the human body mass. It bonds with hydrogen atoms to form water (H2O).In a molecule of water, the mass of oxygen is 32 while that of hydrogen is 2, showing that oxygen is 16 times the mass of hydrogen.Additionally, oxygen forms important organic compounds such as fat, carbohydrates, nucleic acids and proteins, which are the four major biomolecules that exists in nature.HydrogenHydrogen is an element that has an atomic mass of 1. Hydrogen exists as a gaseous molecule that is made up of two atoms of hydrogen.Hydrogen is the simplest element, as its atom contains only a single proton and a single neutron
