A mole of oxygen and a mole of hydrogen have the same quantity of particles, which is approximately 6.022 x 1023 atoms or molecules. However, they differ in their atomic composition, with oxygen having 16 times the Atomic Mass of hydrogen.
In terms of the number of atoms it is 50%. In terms of mass, it is 5.88%.
Cocaine is composed of carbon, hydrogen, and nitrogen. The approximate percent composition of cocaine is around 71.04% carbon, 8.64% hydrogen, and 20.32% nitrogen.
The percent composition of C5H12 is: carbon (C) = 83.78%, hydrogen (H) = 16.22%.
(NH4)2S % Nitrogen = 41.2 % % Hydrogen = 11.8 % % Sulphur = 47 %
To find the percent composition of hydrogen in NH4HCO3, we first calculate the molar mass of the compound. NH4HCO3 has a molar mass of 79.06 g/mol. The molar mass contribution of hydrogen is 1.01 g/mol. To find the percent composition of hydrogen, we divide the molar mass contribution of hydrogen by the molar mass of NH4HCO3 and multiply by 100: (1.01 g/mol / 79.06 g/mol) x 100 ≈ 1.28%.
The compound would need to be combusted to determine the composition. By measuring the amounts of carbon dioxide, water, and nitrogen produced during combustion, we can determine the molar quantities of carbon, hydrogen, and nitrogen in the compound. From these quantities, we can calculate the empirical formula of nicotine.
Mercury has extremely thin atmosphere. It is composed of oxygen (42% by volume), sodium (29%), hydrogen (22%), helium (6%) and other compounds in smaller quantities.
In terms of the number of atoms it is 50%. In terms of mass, it is 5.88%.
The formula of water is H2O. The gram atomic mass of hydrogen is 1.008 and the gram atomic mass of oxygen is 15.999. Therefore, the mass percent composition of hydrogen in water is 100{(2)(1.008)/[(2)(1.008) + 15.999] or 11.19 %.The percent composition of hydrogen in water is: 11,19 %.
Hard to store large quantities of pure hydrogen, very volotile
Simple! Hydrogen.

Jupiter's composition is primarily hydrogen (about 75%) and helium (about 24%). The rest of its composition consists of trace elements such as methane, ammonia, water, and other compounds.
Almost everywhere: e.g. water is made of oxygen and hydrogen; all hydrocarbons (petrol, oil, plastics) contain hydrogen; thus the name. If you mean free hydrogen, then it is in v. smal quantities in the atmosphere, but as its volatile the quantities would be miniscule, if there at all, or in cylinders filled by a hydrogen filling plant.
H20 is the molecular composition of water. Two hydrogen atoms and one oxygen atom. The hydrogen atoms are pulled to the oxygen atom through forces called hydrogen bonding.
It has ice rock and hydrogen
The answers are Hydrogen and Helium.
