Molar and molecular weight of MgF2

• Molecular formula: MgF2 or F2Mg
• Relative molecular weight of MgF2: 62.3018064
• Molar mass of MgF2: 62.3018064 g/mol (0.0623 kg/mol)

Calculation of the relative molecular and molar mass of MgF2

• Mr[MgF2] = Ar[F] * 2 + Ar[Mg] = 18.9984032 * 2 + 24.305 = 62.3018064
• Molar mass (kg/mol) = Mr[MgF2] : 1000 = 62.3018064 : 1000 = 0.0623 kg/mol

MgF2: percent composition by element

• Fluorine (F) = 37.9968064 : 62.3018064 * 100 = 60.988 %
• Magnesium (Mg) = 24.305 : 62.3018064 * 100 = 39.012 %
