Molar and molecular weight of SeF4

• Molecular formula: SeF4 or F4Se
• Relative molecular weight of SeF4: 154.9536128
• Molar mass of SeF4: 154.9536128 g/mol (0.15495 kg/mol)

Calculation of the relative molecular and molar mass of SeF4

• Mr[SeF4] = Ar[F] * 4 + Ar[Se] = 18.9984032 * 4 + 78.96 = 154.9536128
• Molar mass (kg/mol) = Mr[SeF4] : 1000 = 154.9536128 : 1000 = 0.15495 kg/mol

SeF4: percent composition by element

• Fluorine (F) = 75.9936128 : 154.9536128 * 100 = 49.043 %
• Selenium (Se) = 78.96 : 154.9536128 * 100 = 50.957 %
