Molar and molecular weight of Br4Sn

• Molecular formula: Br4Sn or SnBr4
• Relative molecular weight of Br4Sn: 438.326
• Molar mass of Br4Sn: 438.326 g/mol (0.43833 kg/mol)

Calculation of the relative molecular and molar mass of Br4Sn

• Mr[Br4Sn] = Ar[Br] * 4 + Ar[Sn] = 79.904 * 4 + 118.71 = 438.326
• Molar mass (kg/mol) = Mr[Br4Sn] : 1000 = 438.326 : 1000 = 0.43833 kg/mol

Br4Sn: percent composition by element

• Bromine (Br) = 319.616 : 438.326 * 100 = 72.917 %
• Tin (Sn) = 118.71 : 438.326 * 100 = 27.083 %
