1 mole of any element contain 6,022 140 857.1023 atoms (Avogadro number).
2,5 moles of magnesium contain 15,0553521425.1023.
1 mole of CO2 has 1 mole of carbon atoms and 2 moles of oxygen atoms. So, 25 mole of CO2 has 25 moles of carbon atoms and 50 moles of oxygen atoms.
Approx 7.925*10^23 atoms.
85 moles Li x 6.02x10^23 atoms/mole Li = 5.17x10^25 atoms of Li
20 moles x 6.02x10^23 atoms/mole = 1.2x10^25 atoms
15.8 moles Cu x 6.02x10^23 atoms/mole = 9.51x10^22 atoms. There are no molecules in the element Cu (copper). Molecules are found when there are two or more atoms bound together, such as in H2 gas or H2O, etc.
1 mole of CO2 has 1 mole of carbon atoms and 2 moles of oxygen atoms. So, 25 mole of CO2 has 25 moles of carbon atoms and 50 moles of oxygen atoms.
25.0 moles Ca x 6.02x10^23 atoms/mole = 1.50x10^25 atoms
Approx 7.925*10^23 atoms.
85 moles Li x 6.02x10^23 atoms/mole Li = 5.17x10^25 atoms of Li
5.0x10^25 * (1 mol / 6.022x10^23 atoms) = 83 moles of iron.

Diphosphorus pentoxide has 5 oxygen atoms per molecule according to the given prefix. So, 5 moles of it will be 5 x 5 x (6.022x10^23) = 1.51x10^25 oxygen atoms.
The formula unit for calcium is a single atom. Therefore, the number of moles may be found by dividing the given number of atoms by Avogadro's number, or 1.999 moles.
1 mole of silver contains 6.022 X 10^23 atoms 62 moles of silver contains 3.73 X 10^25 atoms of silver
20 moles x 6.02x10^23 atoms/mole = 1.2x10^25 atoms
15.8 moles Cu x 6.02x10^23 atoms/mole = 9.51x10^22 atoms. There are no molecules in the element Cu (copper). Molecules are found when there are two or more atoms bound together, such as in H2 gas or H2O, etc.
Quite a few moles of silver if you mean, 4.59 X 10^25 atoms of silver. 4.59 X 10^25 atoms silver (1 mole Ag/6.022 X 10^23) = 76.2 moles of silver ----------------------------
