Molar and molecular weight of BeF2

• Relative molecular weight of BeF2: 47.0089884
• Molar mass of BeF2: 47.0089884 g/mol (0.04701 kg/mol)

Calculation of the relative molecular and molar mass of BeF2

• Mr[BeF2] = Ar[Be] + Ar[F] * 2 = 9.012182 + 18.9984032 * 2 = 47.0089884
• Molar mass (kg/mol) = Mr[BeF2] : 1000 = 47.0089884 : 1000 = 0.04701 kg/mol

BeF2: percent composition by element

• Beryllium (Be) = 9.012182 : 47.0089884 * 100 = 19.171 %
• Fluorine (F) = 37.9968064 : 47.0089884 * 100 = 80.829 %
