Molar and molecular weight of GaCl2

• Relative molecular weight of GaCl2: 140.629
• Molar mass of GaCl2: 140.629 g/mol (0.14063 kg/mol)

Calculation of the relative molecular and molar mass of GaCl2

• Mr[GaCl2] = Ar[Ga] + Ar[Cl] * 2 = 69.723 + 35.453 * 2 = 140.629
• Molar mass (kg/mol) = Mr[GaCl2] : 1000 = 140.629 : 1000 = 0.14063 kg/mol

GaCl2: percent composition by element

• Gallium (Ga) = 69.723 : 140.629 * 100 = 49.579 %
• Chlorine (Cl) = 70.906 : 140.629 * 100 = 50.421 %
