There is insufficient information for us to even begin to understand this question. Please edit the question to include more context or relevant information. What do you want the percentage for: a particular product, on earth or in the universe?
The percentage of hydrogen in citric acid is 4,198 68 %.
Water has a higher percentage of hydrogen by mass than does hydrogen peroxide, because the latter has equal numbers of hydrogen and oxygen atoms while the former has twice as many hydrogen atoms as oxygen atoms.
The Sun is composed of about 71% hydrogen by mass. This makes hydrogen the most abundant element in the Sun.
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
The molar mass of (NH4)2SO4 is 132.14 g/mol. The molar mass of hydrogen is 1.008 g/mol. Therefore, the percentage by mass of hydrogen in (NH4)2SO4 is (8 × 1.008) / 132.14 * 100 ≈ 6.09%.
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 on earth is just 0.25%
The percentage of hydrogen in citric acid is 4,198 68 %.
By volume, hydrogen accounts for around 0.000055%.

Water has a higher percentage of hydrogen by mass than does hydrogen peroxide, because the latter has equal numbers of hydrogen and oxygen atoms while the former has twice as many hydrogen atoms as oxygen atoms.
The Sun is composed of about 71% hydrogen by mass. This makes hydrogen the most abundant element in the Sun.
Since water is made from two atoms of hydrogen and one atom of oxygen, the percentage of water that is hydrogen is 66% and the percentage of water that is oxygen is 33%. Note that is is NOT percentage of the formula by weight, just by count.
There are 6 hydrogen atoms in C2O6H12. To calculate the percentage of hydrogen in C2O6H12, divide the number of hydrogen atoms by the total number of atoms in the compound (which is 20). So, 6/20 = 0.3 or 30%.
