Well, from info from https://en.wikipedia.org/wiki/Composition_of_the_human_body#Elements and https://en.wikipedia.org/wiki/Standard_atomic_weight
, the human body is composed of primarily these five elements:
_____________Percentages
Element ____mass __atoms gm/mol
-----------------------------------------------------------
Oxygen (O) __65.0 ___24.0 __15.999
Carbon (C) __18.5 ___12.0 __12.011
Hydrogen (H) 9.5 ___62.0 __ 01.0080
Nitrogen (N) __2.6 ___01.1 __14.007
Calcium (Ca)_ 1.3 ___00.22 _40.078
accounting for 96.9% of the mass (and 99.3% of the atoms).
That gives the average molecular mass as
(0.24 * 15.999 gm/mol)
+ (0.12 * 12.011gm/mol)
+ (0.62 * 1.0080 gm/mol)
+ (0.011 * 14.007 gm/mol)
+ (0.0022 * 40.078 gm/mol)
= 6.1483 gm/mol
So every kg is
(1000 g/kg)(1 mol/6.1483 g) = 162.6 mol/kg,
so a person massing in at 50 kg has just under 8130 moles!
I guess ALL living people are well over a mole!
