Calculation of the relative molecular and molar mass of Cs2CO3

• Mr[Cs2CO3] = Ar[C] + Ar[Cs] * 2 + Ar[O] * 3 = 12.0107 + 132.9054519 * 2 + 15.9994 * 3 = 325.8198038
• Molar mass (kg/mol) = Mr[Cs2CO3] : 1000 = 325.8198038 : 1000 = 0.32582 kg/mol

Cs2CO3: percent composition by element

• Carbon (C) = 12.0107 : 325.8198038 * 100 = 3.686 %
