For H2 (natural occurring element Hydrogen) it is 2*1.00794 a.m.u = 2.01588 a.m.e
This means that 1.00000 mole H2 has a mass of 2.01588 grams
The relative molecular mass of hydrogen gas is 2.
Molecular mass of heavy hydrogen(deuterium) is 4 a.m.u. it's Atomic Mass = 2 a.m.u.
Alternatively it can be stated that 1 mole of molecular hydrogen weighs 4 grams.
vapor density =density of gas/density of hydrogen gas=mass of a certain vol. of gas/mass of same vol. of hydrogen gas=mass of n molecules of gas/mass of n molecules of hydrogen gas=mass of 1 molecule of gas/mass of 1 molecule of hydrogen gas=molecular mass of gas/molecular mass of hydrogen gas=molecular mass/22 x vapor density=molecular mass
The gram molecular mass of H2 is 2g.
The atomic mass of hydrogen is 1u. Atomic mass of bromine is 80u. Therefore, the molar mass of hydrogen bromide is 1+80=81u.

vapor density =density of gas/density of hydrogen gas=mass of a certain vol. of gas/mass of same vol. of hydrogen gas=mass of n molecules of gas/mass of n molecules of hydrogen gas=mass of 1 molecule of gas/mass of 1 molecule of hydrogen gas=molecular mass of gas/molecular mass of hydrogen gas=molecular mass/22 x vapor density=molecular mass
The gram molecular mass of H2 is 2g.
On the periodic table it says that one mole of hydrogen atoms weighs 1.008 grams. However, Hydrogen is a diatomic molecule (it is composed of two hydrogen atoms in its molecular state). Hence, the molecular mass of hydrogen is 1.008 multiplied by 2 = 2.016g this is the mass of one mole of hydrogen. Hope this helps!
The molecular mass of hydrogen gas is 2. A molecule of hydrogen gas contains two hydrogen atoms covalently bonded. Since each hydrogen atom has an atomic mass of 1 (as we can derive from the Periodic Table of Elements), the molecular mass of hydrogen gas as a molecule is 1 + 1 = 2.
The atomic mass of hydrogen is 1u. Atomic mass of bromine is 80u. Therefore, the molar mass of hydrogen bromide is 1+80=81u.

The chemical formula of sodium hydrogen carbonate is NH4HCO3.The molecular mass is 84,0066 g.
34.08 g mol-1
Hydrogen has by far the smaller molecular mass (and atomic number) making it the smallest element
This molecular formula is C9H12.
