For this problem, we’re being asked to determine the number of FeF3 molecules found in 24 g FeF3. The flow for this problem will be like this:Mass of FeF3(molar mass of FeF3)→ Moles of FeF3(Avogadro’s number)→ Molecules of FeF3[readmore]• Molar mass of FeF3: The ­atomic mass of Fe is 55.85 g/mol and that of F is 19.00 g/mol. We multiply each atomic mass by the number present in the chemical formula and then add them together to get the molar mass.The molar mass of FeF3 then is:FeF3    1  Fe × 55.85 g/mol Fe  = 55.85 g/mol                       3  F × 19.00 g/mol F = 57.00 g/mol                                          Sum = 112.85 g/mol• Avogadro’s Number: Avogadro’s number gives us the number of entities present in 1 mole: 6.022 × 1023 FeF3 molecules in 1 mole FeF3.Now that we know the values we need, we can now determine the number of FeF3 molecules:24 g FeF3 × 1 mol FeF3112.85  g FeF3×6.022 × 1023 molecules FeF31 mol FeF3= 1.28 x 1023 molecules FeF3.
