Molar and molecular weight of SnCl2

• Molecular formula: SnCl2 or Cl2Sn
• Relative molecular weight of SnCl2: 189.616
• Molar mass of SnCl2: 189.616 g/mol (0.18962 kg/mol)

Calculation of the relative molecular and molar mass of SnCl2

• Mr[SnCl2] = Ar[Cl] * 2 + Ar[Sn] = 35.453 * 2 + 118.71 = 189.616
• Molar mass (kg/mol) = Mr[SnCl2] : 1000 = 189.616 : 1000 = 0.18962 kg/mol

SnCl2: percent composition by element

• Chlorine (Cl) = 70.906 : 189.616 * 100 = 37.395 %
• Tin (Sn) = 118.71 : 189.616 * 100 = 62.605 %
