One mole of a substance is defined by Avogadro as consisting of 6.022 x 1023 atoms. This is Avogadro's number. To calculate the number of atoms in two moles of sodium, use dimensional analysis. 2.0 moles Na x 6.022⋅1023g1mol=1.20⋅1024 atoms of Na.

Because Carbon's Molar Mass is about 12 grams (the actual number is 12.011, which isn't a large enough difference to have an especially relevant effect), this means we have 2 moles of Carbon. In one mole of atoms, there are 6.02*10^23 atoms.

Answer Expert Verified If there are two moles of wolframite, which includes one mole in the formula, multiply the amount of moles in the formula by the amount of moles you have. There are 6.022 x 10^23 atoms in a mole of any element.

As you can see from its molecular formula, there are two Hydrogen atoms in a molecule of Hydrogen. In one mole of Hydrogen gas,there would be6. 02×10^23molecules. In every molecule, there are two atoms, so the number of atoms in 1 mol of hydrogen would be (6.02×10^23)×2=12.04×10^23 atoms.

There are 2 hydrogen atoms in 1 molecule of water. 1 mole of H2O contains 2 moles of H, and each mole of H contains 6.02x10^23 atoms of H.

If we have 2 mol of Na atoms, we have 2 × (6.022 × 10 23) Na atoms, or 1.2044 × 10 24 Na atoms. Similarly, if we have 0.5 mol of benzene (C 6H 6) molecules, we have 0.5 × (6.022 × 10 23) C 6H 6 molecules, or 3.011 × 10 23 C 6H 6 molecules. A mole represents a very large number!

How many atoms are present in 0.147 mole of F2? One molecule of F2 contains 2 atoms of fluorine. So, 0.147 moles will contain 0.147 X 2 X 6.023 X 1023 = 1.76 X 1023 atoms of flourine.

Since 1 mole of silicon contains 6.023 x 10^23 atoms, 4 moles will contain: (4 moles) x (6.023 x 10^23 atoms) = 2.4092 x 10^24 atoms. Thus, 4 moles of the silicon element contains about 2.4 x 10^24 atoms.

1 mole of atom=6.022×10^(23)atoms. Finally,1 mole of molecules=6.022×10^(23) molecules. Mole is one of the standard unit of measurement used throughout world for counting if large no. of objects such as ions, atoms, molecules etc.

If you have a mole of cl2, then you have 6.02 * 10^23 molecules of cl2. If you want to calculate for atoms however, you can see that each molecule has two atoms of cl. Therefore you have 2* 6.02 * 10^23 chlorine atoms.

If you have a compound like H2O, then: one mole of water contains 6.02 x 1023 MOLECULES of water. But each molecule of water contains 2 H and 1 O atom = 3 atoms, so there are approximately 1.8 x 1024 atoms in a mole of water.

023 × 10^23 similarly 0.25 mole will contain 0.25 × 6.023 × 10^23. So 0.25 mole of silver also contain 0.25 × 6.023 × 10^23 atoms. The number of particles, in this case silver, in a mol of anything is 6.022×10^23 atoms or molecules or cars what it is does not matter as it is the same number for anything you choose.
