What particle are you counting (atoms, molecules, or formula units) if you use Avogadro's number to count particles of a) salt (NaCl) b) sugar (sucrose) c) baking soda (sodium Bicarbonate)

What particle are you counting (atoms, molecules, or formula units) if you use Avogadro's number to count particles of

a) salt (NaCl) formula units

b) sugar (sucrose)molecules

c) baking soda (sodium Bicarbonate)formula units

Explanation:

Avogadro's  Number, unit per mole (mole⁻¹) is factor of the number of particles present in one mole of a substance which may be ions, molecules, atoms or electrons. The Avogadro's number is denoted by NA, and the value of Avogadro's number is 6.02214076 × 10²³.

The Avogadro constant, usually denoted by NA or L is the factor that, multiplied by the amount of substance in a sample, measured in moles, gives the number of constituent particles in that sample. Its unit is the reciprocal of mole, and it is defined as NA = 6.02214076×10²³

For

a) salt (NaCl), the Avogadro's number tells how many formula units of NaCl are present in a mole of NaCl. NaCl is an ionic compound and not a molecule

When the number of formula units present are known, the number of the constituent elements can be ascertained.

b) Sugar, sucrose is a molecule and the Avogadro's number indicates the number of molecules present in a sample of sugar

c) Baking Soda is an ionic compound also measured in formula units.

there all right good
