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).
---- Mass substance ----- X 6.022 x 1023 formula units
Molar mass substance
CONVERSION FACTOR
Mass (g) substance x 1 mol substance ------- x ----- Avogadro's number
/////////////////// molar mass (g) substance ------------ 1 mol substance
