Calculation of the relative molecular and molar mass of KC2H3O2

• Mr[KC2H3O2] = Ar[C] * 2 + Ar[H] * 3 + Ar[K] + Ar[O] * 2 = 12.0107 * 2 + 1.00794 * 3 + 39.0983 + 15.9994 * 2 = 98.14232
• Molar mass (kg/mol) = Mr[KC2H3O2] : 1000 = 98.14232 : 1000 = 0.09814 kg/mol

KC2H3O2: percent composition by element
