Explain what a mole of copper (Cu) atoms and a mole of Sulfur Dioxide (SO2) molecules have in common.

The amount of molecules → 6.02*10²³

Explanation:

Avogadro Number (NA) is the amount of particles that are contained in 1 mol of anything.

It does not matter the mass of compounds, or molecules, 1 mol has 6.02*10²³ particles, the same number for every compound.

1 mol of H₂O that weighs 18 grams has 6.02*10²³ molecules

1 mol of sucrose, that weighs 342 g has 6.02*10²³ molecules

Generally, the NA is the number of atoms in 12 grams of the carbon-12 isotope.
