Molar and molecular weight of F4Se

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

Calculation of the relative molecular and molar mass of F4Se

• Mr[F4Se] = Ar[F] * 4 + Ar[Se] = 18.9984032 * 4 + 78.96 = 154.9536128
• Molar mass (kg/mol) = Mr[F4Se] : 1000 = 154.9536128 : 1000 = 0.15495 kg/mol

F4Se: percent composition by element

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