Molar and molecular weight of Ca(MnO4)2

• Molecular formula: Ca(MnO4)2 or CaMn2O8
• Relative molecular weight of Ca(MnO4)2: 277.94929
• Molar mass of Ca(MnO4)2: 277.94929 g/mol (0.27795 kg/mol)

Calculation of the relative molecular and molar mass of Ca(MnO4)2

• Mr[Ca(MnO4)2] = Ar[Ca] + Ar[Mn] * 2 + Ar[O] * 8 = 40.078 + 54.938045 * 2 + 15.9994 * 8 = 277.94929
• Molar mass (kg/mol) = Mr[Ca(MnO4)2] : 1000 = 277.94929 : 1000 = 0.27795 kg/mol

Ca(MnO4)2: percent composition by element

• Calcium (Ca) = 40.078 : 277.94929 * 100 = 14.419 %
• Manganese (Mn) = 109.87609 : 277.94929 * 100 = 39.531 %
• Oxygen (O) = 127.9952 : 277.94929 * 100 = 46.05 %
