- Calculating theFormula Mass of a Compound.Balance theChemical Equation:Mg + N₂ → Mg₃N₂
-
- Identify the molarmass of every element:Molar mass of Mg =24.305 g/mol (24.305)(3) = 72.915 g MgMolar Mass of N =14.0067 g/mol (14.0067)(2) = 28.0134 g N
- Add the totalmolar mass to find the mass of the compound:m = ∈(molar masses per element)m = 72.915g +28.0134molar mass ofMg₃N₂ = 100.9284 g/mol
