In one mole of hydrogen atoms, there exists approximately 6.02⋅1023 hydrogen atoms.

Explanation: One mole of methane specifies NA , Avogadro's number of methane molecules, i.e. 6.022×1023 individual CH4 molecules. And thus it contains 4×6.022×1023 hydrogen atoms .

1 water molecule = 2 Hydrogen atoms + 1 oxygen atom. So, 1 mole H2O = 1.2044×10^24 hydrogen atoms. Therefore 2 mole H2O will have 2.4088×10^24 hydrogen atoms.

The atomic mass of hydrogen is 1 g/mole. To make up 1 kilogram or 1000 g of hydrogen element, 1000 moles of hydrogen is required. Each mole has a Avogadro's number of atoms or 6.023 xx 10^(23) atoms. Thus, 1 kg hydrogen element or 1000 moles of hydrogen have 6.023 xx 10^(26) atoms (or 1000 times the Avogadro's number).

Number of H atom in 1 mole H2 is 2×6.022 × 10^23 atom.

1 mole = 6.022 x 10^23 atoms or molecules or formula units of that substance. Calculation of mole from number of particles and vice – versa. Here, 2 moles of N2 molecules will have 2x2 moles of N atoms or particles. So, 4 mole of N atoms = 4 x 6.022 x 10^23 atoms of Nitogen.

Now, in two moles of H2, 12.044 × 10^(23) molecules are present and in 1 molecule of H2, two H atoms are present.

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.

Therefore 2 moles will have 1.204*10^24 molecules of NH3. There are 4 atoms in each molecule, so 2 moles will have 4*(1.204*10^24) atoms which is 4.816*10^24 atoms. How many atoms of hydrogen are present in 1.7g of NH3?

Since, one molecule of (NH4) 2SO4 contains 8 atoms of hydrogen . So one mole of (NH4)2 SO4 contains (6.022×10^23)×8 atoms. So we can easily say that it has 8 moles of hydrogen atom.

Molecules of hydrogen gas are represented as . The molecular mass of hydrogen gas is 2 g/mole. To make up for 1 kg hydrogen or 1000 gm of hydrogen gas, we need 500 moles of hydrogen gas. These many moles of hydrogen gas will have atoms (500 times the Avogadro's number of atoms).

One mole of sulfur atoms has a mass of 32.065 g/mol. One mole of sulfur atoms is Avogadro's number of atoms, which is 6.02 x 1023 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 3: Hydrogen has an atomic mass of 1.01 atomic mass units.

One mole (abbreviated mol) is equal to 6.022×1023 molecular entities (Avogadro's number), and each element has a different molar mass depending on the weight of 6.022×1023 of its atoms (1 mole).
986845
Thus we must consider the makeup of an H2 molecule, where we see that it is a diatomic molecule. Thus we must multiply 6.022 * 1023 by 2 to calculate the number of individual atoms present in 1 mole of H2. We find our answer to be 1.2044 * 1024.

One MOLE of hydrogen atoms contains the same number of atoms as the number of hydrogen molecules in one MOLE of hydrogen molecules, i.e., Avagadros number. However, one mole of hydrogen atoms has a mass of 1 gram while one MOLE of hydrogen molecules has a mass of 2 grams.
