Answer:
Step-by-step explanation:
In the case of NaCl
Formula units, also known as formula mass, are the simplest repeating unit in a chemical compound. For a salt like sodium chloride (NaCl), one formula unit would be one Na+ ion and one Cl- ion.
For sodium chloride, the formula mass is the sum of the atomic masses of the individual atoms in the formula unit, which is approximately 58.44 g/mol.
In the case of NaCl, 24 g would be equivalent to approximately 0.41 moles. Since one formula unit of NaCl weighs 58.44 g, then 0.41 moles of NaCl would be equal to approximately 0.41 moles * 6.022 x 10^23 formula units = 2.47 x 10^23 formula units.
Therefore, 24 g of NaCl would be equal to approximately 2.47 x 10^23 formula units.
