Now, in two moles of H2, 12.044 × 10^(23) molecules are present and in 1 molecule of H2, two H atoms are present. As we know 1mole of any element has 1NA molecule. And 1NA=6.022*10′23 atom.

Because the molecular mass of Hydrogen is 1gram/mole, there is 1 mole of hydrogen in 1 gram of hydrogen atoms. For every mole, there are 6.02*10^23 atoms so in 1 gram of hydrogen there are 6.02*10^23 hydrogen atoms (in scientific notation) this is equal to 602000000000000000000000 hydrogen atoms.

Answer: 1 mole of anything contains 6.02 x 1023 particles. (Note that "mol" is the abbreviation for mole.) So, 4.21 mol of hydrogen gas contains 4.21 x 6.02 x 1023 = 2.53 x 1024 molecules of hydrogen.

One sulfuric (H2SO4) molecule has 2 hydrogen atoms, 1 sulfur atom, and 4 oxygen atoms. You can also say one mole of sulfuric acid has two mols of hydrogen atoms, 1 mol of sulfur atoms, and 4 moles of oxygen atoms.

In other words, 1 mole of atoms is 6.02×1023 atoms. 1 mole of molecules is 6.02×1023 molecules.

Recall that two hydrogen atoms bind to make a hydrogen molecule. The same can be said of one mole of any other substance where two atoms combine to make a simple molecule. A mole of oxygen atoms 16 grams while a mole of oxygen molecules is 32 grams.

4 grams (2 moles) of hydrogen molecules contains 4 moles of hydrogen atoms. 1 mole of hydrogen atoms corresponds to 6. 023×1023 atoms.

One sulfuric (H2SO4) molecule has 2 hydrogen atoms, 1 sulfur atom, and 4 oxygen atoms. You can also say one mole of sulfuric acid has two mols of hydrogen atoms, 1 mol of sulfur atoms, and 4 moles of oxygen atoms. So in total, we have 7 mols of atoms.

Expert Answers info One mole of any substance contains Avogadro's number of atoms = 6.022 x 10^23 atoms. So multiply number of moles x number of atoms/mole = 1.8066 x 10^24 atoms of H2.

The number 6.022 x 1023 is the value of the Avogadro's number. It is the number of particles or substance in one mole. For example, there are 6.022 x 1023 atoms in one mole of hydrogen.

Notice that you have two hydrogen atoms per formula unit of sulfuric acid. This means that one mole of sulfuric acid will contain 2 moles of hydrogen atoms. The molar mass of sulfuric acid is 98.0795 g/mol .

A mole of a compound will have 6.02 x 10^23 molecules, so the number of atoms in a mole is 6.02 x 10^23 x number of atoms in a molecule. One Molecule of Ca(OH)2 has 5 atoms. Therefore, one mole of Ca(OH)2 has 6.022 x10^23 x 5 = 30.11 x 10^23 atoms.

From the previous answer we can see= 1mole H2S molecule = 1 mole sulfur atom=6.023*1023 S atoms.

These numbers are either in atomic mass units (amu), or in grams per mole of atoms. This means that 1 MOLE of hydrogen atoms will weigh 1.008 grams. That said, to find the mass of one ATOM, we need to convert from moles to atoms as follows: 1.008 grams/mole Hydrogen * (1 mole/6.022x10^23 atoms) = 1.67 x 10^24grams.

So, 1 mole of Methane contains 1 mole of Carbon Atoms and 4 moles of Hydrogen atoms. In other words 6 x 1023 Carbon atoms and 24 x 10 23 Hydrogen atoms.
