Molar and molecular weight of SnBr4

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

Calculation of the relative molecular and molar mass of SnBr4

• Mr[SnBr4] = Ar[Br] * 4 + Ar[Sn] = 79.904 * 4 + 118.71 = 438.326
• Molar mass (kg/mol) = Mr[SnBr4] : 1000 = 438.326 : 1000 = 0.43833 kg/mol

SnBr4: percent composition by element

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