It depends on the substance and its molar mass.
In order to convert from grams to formula units, you must first convert grams to moles, then moles to formula units (grams --> moles --> formula units).
1. Divide the mass (g) of the given substance by the substance's molar mass.
2. Multiply the number of moles found in Step 1 (above) by Avogadro's number (6.022 x 1023).

How many molecules are in 7.4 g H'S?
By definition, Avogadro's Number is the number of molecules or formula units in the number of grams corresponding to the gram molecular weight or gram formula unit, and by experiment, Avogadro's Number is about 6.022 X 1023. Therefore, 7.75 X 1025 formula units contains (7.75 X 1025/6.022 X 1023) or 1.29 X 102 moles or formula units, to the justified number of significant digits.
