How many molecules of sulfur trioxide are in 78.0 grams?
By definition there are #6.022140857(74)×10^23# individual #SO_3# molecules in #80.066##g# of this material. This represents the MOLAR MASS of sulfur trioxide.
To find the number of #SO_3# molecules, I simply divide the mass by the molar mass, to get a quantity in moles, and mulitply this number by #”Avogadro’s number, “6.022140857(74)×10^23#, which is the number of molecules that have a #80.066*g# mass:

ChemTeam: Using Avogadro's Number in Calculations – Problems 1-10 – How many grams of C are there in a sample of C that contains the same number of moles as a 47.8 gram sample of P? Converting from Mass to Number is an example of where more than one conversion factor is necessary: 15.0 grams copper = ? atoms of copper.Grams to Moles conversion and vice versa, converts weight and molarity of chemical compounds. As2O3 Arsenic Trioxide (Arsenic(III) Oxide). AsCl3 Arsenic Trichloride. AuCl3 Gold(III) Chloride. E.g. Molar mass of NaCl is 58.443, how many grams is 5 mole NaCl? grams = 58.443 × 5 = 292.215 (g).Once we know how many valence electrons there are in SO3 we can distribute them around the central atom with the goal of filling the outer shells of In the Lewis structure of SO3 structure there are a total of 24 valence electrons. SO3 is also called Sulfur trioxide. Note that SO3 can have an…
