In naturally occurring hydrogen, most of the mass is that of the hydrogen-1 isotope.
By mole, water is 66.666r% hydrogen but by mass it is about 11.9% hydrogen.
21.2 %
Percentage of hydrogen in methane is 25%. Percentage of hydrogen = mass of hydrogen/mass of methane x 100 mass of hydrogen = 1 x 4= 4 and mass of carbon = 12. Since methane has 4 hydrogen atoms and one carbon atom therefore mass of methane = 16 Percentage of hydrogen = 4/16 x 100 =25

Mass of ammonia is 17. Mass of Hydrogen in it is 3. So the percentage of hydrogen by mass is 17.64%

The percentage by mass of sodium (Na) in a formula unit of sodium hydrogen carbonate (NaHCO3) is 27,38 %.
Percentage of hydrogen in methane is 25%. Percentage of hydrogen = mass of hydrogen/mass of methane x 100 mass of hydrogen = 1 x 4= 4 and mass of carbon = 12. Since methane has 4 hydrogen atoms and one carbon atom therefore mass of methane = 16 Percentage of hydrogen = 4/16 x 100 =25
11% Hydrogen and 89% Oxygen
98%
The percentage of H in ammonium phosphate is the mass of H divided by the mass of the entire compound.
It all depends on what you're looking for. If you mean ratio of atoms, It is a one:one ratio, so 50% each If you mean mass, 1.0125% of the mass of one molecule is hydrogen and the other 98.9875% is bromine.
