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 gram molecular mass of hydrogen is 1 gram per mole.
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
For H2 (natural occurring element Hydrogen) it is 2*1.00794 a.m.u = 2.01588 a.m.eThis means that 1.00000 mole H2 has a mass of 2.01588 grams
The molecular mass of hydrogen sulfide (H2S) is 34.08 grams per mole.
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 molecular formula of the compound is NH4NO3, which is ammonium nitrate. This compound contains nitrogen, hydrogen, and oxygen elements, with a molecular mass of approximately 63.008 amu.
The molecular mass of NaHSO4 (sodium hydrogen sulfate) is approximately 120.06 g/mol.
Table sugar (sucrose) has a molecular formula of C12H22O11, which means it is composed of carbon, hydrogen, and oxygen. To calculate the percentage by mass of hydrogen in table sugar, divide the mass of hydrogen by the total mass of the compound and then multiply by 100. In this case, hydrogen has a total mass of 22 g/mol out of a total molecular mass of 342 g/mol, which gives a percentage of approximately 6.4% hydrogen by mass in table sugar.
Each chloroform molecule (CHCl3) is composed of 25% hydrogen by mass. This is because the molecular weight of hydrogen is 1, with one hydrogen atom in each chloroform molecule, and the molecular weight of chloroform is 119.38.
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 chemical formula of sodium hydrogen carbonate is NH4HCO3.The molecular mass is 84,0066 g.
The molecular mass of water (H2O) is 18, which means the total mass of one oxygen atom and two hydrogen atoms is 18. Since the atomic mass number of hydrogen is 1, the atomic mass of oxygen can be calculated as 16 (18 - 2).
