The percentage of hydrogen in citric acid is 4,198 68 %.
By mole, water is 66.666r% hydrogen but by mass it is about 11.9% hydrogen.
In naturally occurring hydrogen, most of the mass is that of the hydrogen-1 isotope.
the percentage of these three gases in the air is as follows: Methane: 0.00002% Krypton: 0.00011% Hydrogen: 0.00005%
21.2 %
Mass of ammonia is 17. Mass of Hydrogen in it is 3. So the percentage of hydrogen by mass is 17.64%
The percentage of hydrogen in citric acid is 4,198 68 %.
