Mass of ammonia is 17. Mass of Hydrogen in it is 3. So the percentage of hydrogen by mass is 17.64%
The intermolecular forces are hydrogen bonding.
Ammonia is a compound. It consists of the elements nitrogen and hydrogen. In one ammonia molecule, there is one nitrogen atom and three hydrogen atoms. The chemical formula for ammonia is NH3.
Hydrogen gas has the lowest mass out of ammonia, bromine, hydrogen and chlorine, so it would have the highest velocity for a given kinetic energy.
Two molecules of ammonia contain 6 hydrogen atoms.
The mass of 3 mol of ammonia is 51,093 g; the number of ammonia molecules in 3 moles is18,066422571.10e23.
The formula for ammonia is NH3, and to a reasonable approximation, the atomic weight of hydrogen is 1 and that of nitrogen is 14. Therefore, the % hydrogen = 100(3/17) = 18 %.
Ammonia contains about 82.35 % nitrogen by mass.
NH3 which is ammonia has the highest percentage by mass of nitrogen.
Molar mass of ammonia = (14.01 + 3.03) (Molar mass of nitrogen + 3 times molar mass of hydrogen, as chemical formula of ammonia is NH3). Molar mass= 17.04 Molar mass x moles = mass 17.04 x 3 = 51.12 Mass of 3 moles of ammonia is 51.12g.
Molar mass of ammonia is 17.031 whereas molar mass of hydrogen chloride (or hydrochloric acid) is 36.461. Hence if given masses, there is 1 mole ammonia and 2 moles HCl. Hence there is more number of hydrogen chloride.
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.

The equation for the reaction is N2 + 3 H2 -> 2 NH3. The gram atomic mass of nitrogen is 14.0067, and the gram atomic mass of hydrogen is 1.00794. Therefore, the mass fraction of nitrogen in ammonia is 14.0067/[14.0067 + (3*)(1.00794)] or about 0.8225, and, since nitrogen and hydrogen are the only two elements present, the mass fraction of hydrogen is 1*- 0.8225 or about 0.1775. The mass fraction of nitrogen in the amounts of nitrogen and hydrogen specified is 44.5/(44.5 + 2.58) or about 0.945. Therefore, hydrogen is the limiting reactant in this mixture, and the mass of ammonia produced is 2.58/0.1775 or 14.5 grams, to the justified number of significant digits. ________________ *An exact integer.
The percentage by mass of sodium (Na) in a formula unit of sodium hydrogen carbonate (NaHCO3) is 27,38 %.
One mole approximately weighs 17g.So 3 moles have a mass of 51g.
