I have the molar mass, sample mass and # of moles of a substance.how do i find the #of molecules/formula units

how do i find the number of molecules or formula units of substances/compounds? for each compound, i have the molar mass (g/mol), sample mass in grams, and number of moles

Answer:
Molar mass (? g/1 mol)
Sample mass (? g)?
Avagadro's Number (6.022 x 10^23 units/mole)

sample mass x molar mass x avagadro's number

(? g) x (1 mol/? g) x (6.022x10^23units/1 mol) = units or molecules or atoms

The number of molecules is represented by Avogadro's number = 6.022 * 10^23 molecules per mole. Use the appropriate conversion to change from moles to molecules.
