There are those who want to know the molar mass of aluminum fluoride. Aluminum fluoride is a compound of aluminum and fluorine. To know its molar mass, the relative atomic mass of aluminum and fluorine should be determined.

The relative atomic mass of aluminum is about 27, and the relative atomic mass of fluorine is about 19. The chemical formula of aluminum fluoride is AlF 🥰, which consists of an aluminum atom and a trifluoride atom.

Its molar mass is obtained by summing the relative atomic mass of each atom according to its quantity in the chemical formula. That is, the relative atomic mass of one atom of aluminum is 27, and the relative atomic mass of the three atoms of fluorine is 19 × 3 = 57.

So the molar mass of aluminum fluoride is 27 + 57 = 84g/mol. It can be seen that the molar mass of aluminum fluoride is 84 grams per mole.
