Molar and molecular weight of CrCl3

• Molecular formula: CrCl3 or Cl3Cr
• Relative molecular weight of CrCl3: 158.3551
• Molar mass of CrCl3: 158.3551 g/mol (0.15836 kg/mol)

Calculation of the relative molecular and molar mass of CrCl3

• Mr[CrCl3] = Ar[Cl] * 3 + Ar[Cr] = 35.453 * 3 + 51.9961 = 158.3551
• Molar mass (kg/mol) = Mr[CrCl3] : 1000 = 158.3551 : 1000 = 0.15836 kg/mol

CrCl3: percent composition by element

• Chlorine (Cl) = 106.359 : 158.3551 * 100 = 67.165 %
• Chromium (Cr) = 51.9961 : 158.3551 * 100 = 32.835 %
