If the open-angle glaucoma is not specified as primary, assign code 365.10. The residual stage of open-angle glaucoma is classified to code 365.15. Assign code 365.01 for open-angle glaucoma with borderline intraocular pressure.
Return to Mole Menu. Percent composition is the percent by mass of each element present in a compound. Water, H2O, is the first example. One mole of water is 18.0152 grams. In that compound, there are two moles of H atoms and 2 x 1.008 = 2.016 grams. That's how many grams of hydrogen are present in one mole of water.
The composition of the human body can be looked at from the point of view of either mass composition or atomic composition. To illustrate both views, the adult male human body is approximately 57% water, and water is 11% hydrogen by mass but 67% by count of atoms (i.e. 67 atomic percent). Thus, most of the mass of the human body is oxygen, but most of the atoms in the human body are hydrogen atoms. Both mass-composition and atomic composition figures are given below (see pie graphs and table).
