Molar and molecular weight of Cl2Mn

• Molecular formula: Cl2Mn or MnCl2
• Relative molecular weight of Cl2Mn: 125.844045
• Molar mass of Cl2Mn: 125.844045 g/mol (0.12584 kg/mol)

Calculation of the relative molecular and molar mass of Cl2Mn

• Mr[Cl2Mn] = Ar[Cl] * 2 + Ar[Mn] = 35.453 * 2 + 54.938045 = 125.844045
• Molar mass (kg/mol) = Mr[Cl2Mn] : 1000 = 125.844045 : 1000 = 0.12584 kg/mol

Cl2Mn: percent composition by element

• Chlorine (Cl) = 70.906 : 125.844045 * 100 = 56.344 %
• Manganese (Mn) = 54.938045 : 125.844045 * 100 = 43.656 %
