Molar and molecular weight of NaMnO4

• Molecular formula: NaMnO4 or MnNaO4
• Relative molecular weight of NaMnO4: 141.92541428
• Molar mass of NaMnO4: 141.92541428 g/mol (0.14193 kg/mol)

Calculation of the relative molecular and molar mass of NaMnO4

• Mr[NaMnO4] = Ar[Mn] + Ar[Na] + Ar[O] * 4 = 54.938045 + 22.98976928 + 15.9994 * 4 = 141.92541428
• Molar mass (kg/mol) = Mr[NaMnO4] : 1000 = 141.92541428 : 1000 = 0.14193 kg/mol

NaMnO4: percent composition by element

• Manganese (Mn) = 54.938045 : 141.92541428 * 100 = 38.709 %
• Sodium (Na) = 22.98976928 : 141.92541428 * 100 = 16.198 %
• Oxygen (O) = 63.9976 : 141.92541428 * 100 = 45.092 %
