Avagadro's number = 6.022 × 1023 atoms/mol
0.5 mol × (6.022 × 1023) atoms/mol = 3.011 ×1023 atoms
1 mole NH3 (3 mole H/1 mole NH3) = 3 mole hydrogen atoms
One mole of hydrogen molecules (H2) contains 2 hydrogen atoms per molecule, while one mole of hydrogen atoms contains single hydrogen atoms. Since the mass of a hydrogen atom is approximately half the mass of a hydrogen molecule, the molar mass of hydrogen molecules is higher than the molar mass of hydrogen atoms.
No, 1 mole of hydrogen atoms does not equal 1 mole of helium atoms. One mole of any element contains Avogadro's number of atoms (6.022 x 10^23), so 1 mole of hydrogen atoms would have that many hydrogen atoms, while 1 mole of helium atoms would have that many helium atoms.
Because each hydrogen molecule contains 2 hydrogen atoms!
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.
divide the mass of the hydrogen by the molar mass.
The hydrogen molecule is diatomic, H2.
There are 16 hydrogen atoms in 1 mole of C7H16.
In one mole of hydrogen peroxide (H2O2), there are two moles of oxygen atoms.
One mole of any substance contains 6.022x10 to the power of 23 molecules of that substance. A water molecule contains two hydrogen atoms so one molecule of water has 12.044x10 to 23 hydrogen atoms.
1 mole of any element = 6.02 × 1023 atoms
There are 2 hydrogen atoms in each formula unit of Na2HPO4.
