Biology
1 answer:
topjm [15]2 years ago
4 0

Answer:

7 followed by 27 zeros

Explanation:

The body of an adult man weighing 70 kg is made up of approximately 6.7 • 10 ^ 27 atoms.

The body of an adult male contains approximately 57% water, but if we look by weight, hydrogen is only 11%, while if we look at the mutual ratio of atoms in water, there are a total of 67% hydrogen atoms.

In this way, most of the weight (mass) of the human body comes from oxygen, but most of the atoms in the body are hydrogen.
