Calculation of the relative molecular and molar mass of KNaCO3

• Mr[KNaCO3] = Ar[C] + Ar[K] + Ar[Na] + Ar[O] * 3 = 12.0107 + 39.0983 + 22.98976928 + 15.9994 * 3 = 122.09696928
• Molar mass (kg/mol) = Mr[KNaCO3] : 1000 = 122.09696928 : 1000 = 0.1221 kg/mol

KNaCO3: percent composition by element

• Carbon (C) = 12.0107 : 122.09696928 * 100 = 9.837 %
• Potassium (K) = 39.0983 : 122.09696928 * 100 = 32.022 %
• Sodium (Na) = 22.98976928 : 122.09696928 * 100 = 18.829 %
• Oxygen (O) = 47.9982 : 122.09696928 * 100 = 39.312 %
