Trick question. Hydrogen is a diatomic molecule; it travels around with a buddy as H2 and not as a single atom. This is generally true of all gases except the inert gases. By definition, a mole of anything has 6.022 x 1023 "units" of that stuff. (That's Avogadro's number.) The "stuff" is the atoms or the molecules of that "stuff" and it can be thought of in terms of the "reaction units" of that stuff. We do not have H2 + O = H2O. We have 2H2 + O2 = 2H2O because oxygen is diatomic like hydrogen. The "reaction units" of hydrogen and oxygen are H2 and O2 respectively. Now the answer will appear. A mole of hydrogen is 6.022 x 1023 units of hydrogen which will be 6.022 x 1023 molecules of hydrogen which will be (6.022 x 1023 times 2) atoms of hydrogen which will be 1.204 x 1024 atoms of hydrogen.
divide the mass of the hydrogen by the molar mass.
The hydrogen molecule is diatomic, H2.
In one mole of water (H2O), there are 2 moles of hydrogen atoms (H) due to the formula H2O having 2 hydrogen atoms. Since 1 mole of hydrogen contains Avogadro's number of atoms (6.022 x 10^23), in a mole of water there are 2 times Avogadro's number of hydrogen atoms, which equals 1.2044 x 10^24 atoms.
CH3COOH CH3COO- + H+So there is only one acidic H atom.[Only the 'bold' H atom is acidic, the 3 'methyl' H's are not!]
2 moles C8H18 (18 moles H/1 mole C8H18) = 36 moles of hydrogen =================
divide the mass of the hydrogen by the molar mass.
There are 16 hydrogen atoms in 1 mole of C7H16.
1 mole NH3 (3 mole H/1 mole NH3) = 3 mole hydrogen atoms
593 g H2O x 1 mol/18 g x 2 mole H/mole H2O x6.02x10^23 H atoms/mole H = 4x10^25 atoms of H

2.95 mole H2O (2 moles H/1 mole H2O) = 5.90 moles hydrogen ------------------------------

Quite a few! 871 grams water (1 mole H2O/18.016 grams)(2 moles H/1 mole H2O)(6.022 X 1023/1 mole H) = 5.82 X 1025 atoms of hydrogen ========================
2 moles C8H18 (18 moles H/1 mole C8H18) = 36 moles of hydrogen =================
In 0.86 moles of CH4, you have 5.16 x 10^23 atoms of hydrogen. This is because there are four hydrogen atoms in one molecule of CH4, making a total of 0.86 x 4 = 3.44 moles of hydrogen atoms, which can be converted to atoms using Avogadro's number.
11.5 mole H2O (2 mole H/1 mole H2O)(6.022 X 10^23/1 mole H)(1 mole H/6.022 X 10^23) = 23.0 moles of H atoms
