To convert moles into atoms, you need to use Avogadro's number, which is 6.022 x 10^23 atoms per mole. Simply multiply the number of moles by Avogadro's number to get the number of atoms. For example, if you have 2 moles of a substance, you would multiply 2 moles by 6.022 x 10^23 atoms/mole to get 1.2044 x 10^24 atoms. This conversion is important in chemistry when working with large quantities of atoms.
Thirty two grams of sulfur contains approximately 1.0 x 10^23 sulfur atoms. This is calculated by converting the mass to moles and then using Avogadro's number to determine the number of atoms in that many moles.
There are 1.5 x 10^23 atoms of oxygen in 44g of CO2. This can be calculated by converting the mass of CO2 to moles, using the molar mass to find the number of moles of oxygen, and then multiplying by Avogadro's number to find the number of atoms.

There are twice as many oxygen atoms as carbon atoms in carbon dioxide, so 100.0 moles of carbon dioxide would contain 200.0 moles of oxygen atoms.
In 0.800 moles of MgO, there are the same number of oxygen atoms as there are in 0.800 moles of O atoms. One mole of MgO contains one mole of oxygen atoms, which is equivalent to 6.022 x 10^23 oxygen atoms.
1 mole of water is 18g. 36g of water is thereforeequivalent to 2 moles. 2 moles of water contains 4 moles of hydrogen and 2 moles of oxygen and so there are6 moles of atoms in 2 moles of water. 6 moles of atoms x (3.6x10^24) = 36.1x10^24 atoms
The formula for converting is: atoms ÷ Avogadro's constant = # moles (1.8 × 1023) ÷ (6.02 × 1023)= 0.299 moles Cu

There are 1.68 x 10^24 atoms of sulfur in 280g of a 50% H2SO4 solution. This can be calculated by first finding the moles of H2SO4 in the solution, then using the molar ratio to find the moles of sulfur, and finally converting moles to atoms using Avogadro's number.
There are only two reverse operations.
3.9 moles of atoms
1,638 moles contain 9,864266723766.10e23 atoms.

This is equivalent to 1,4 moles.
There are twice as many oxygen atoms as carbon atoms in carbon dioxide, so 100.0 moles of carbon dioxide would contain 200.0 moles of oxygen atoms.
