Molar and molecular weight of CaCl2O8

• Molecular formula: CaCl2O8 or Ca(ClO4)2
• Relative molecular weight of CaCl2O8: 238.9792
• Molar mass of CaCl2O8: 238.9792 g/mol (0.23898 kg/mol)

Calculation of the relative molecular and molar mass of CaCl2O8

• Mr[CaCl2O8] = Ar[Ca] + Ar[Cl] * 2 + Ar[O] * 8 = 40.078 + 35.453 * 2 + 15.9994 * 8 = 238.9792
• Molar mass (kg/mol) = Mr[CaCl2O8] : 1000 = 238.9792 : 1000 = 0.23898 kg/mol

CaCl2O8: percent composition by element
