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

The prime reason for this is that an atom of oxygen comprises sixteen times more mass in comparison to a hydrogen atom.

Explanation:

This means that A orginasim will appear to contain more oxygen, but the size diffrence will mean that there will be more hydrogen, just of a smaller size with less mass, thus making up a lesser part of the organism in terms of mass, but the majority on the molecular level.

Reason 1: The mass of Oxygen is 16 times that of Hydrogen. Hydrogen takes 16 atoms to equal the mass of 1 Oxygen atom.

Reason 2: A large portion of an organism’s mass is in the form of water. Water contains two hydrogen atoms and one oxygen atom.

instead of copying and pasting things off of tests or work done on computer which im sure you did, try and read over the question carefully
