You have to go from grams --> moles --> molecules. You can find the equation online.

First you have to find the molar mass of AlF3 which is 83.98 g/mol.

To convert it to moles you simply

450.0 grams ×
(1 mol)/(83.98 grams) = 5.358 mol

To convert mol to molecules: (multiply by Avogadros # = 6.022*10^23)

5.358 mol ×
(6.022*10^2^3)/(1mol) =
3.23 *10^(24)
