Molar and molecular weight of Cs2SO4

• Molecular formula: Cs2SO4 or Cs2O4S
• Relative molecular weight of Cs2SO4: 361.8735038
• Molar mass of Cs2SO4: 361.8735038 g/mol (0.36187 kg/mol)

Calculation of the relative molecular and molar mass of Cs2SO4

• Mr[Cs2SO4] = Ar[Cs] * 2 + Ar[O] * 4 + Ar[S] = 132.9054519 * 2 + 15.9994 * 4 + 32.065 = 361.8735038
• Molar mass (kg/mol) = Mr[Cs2SO4] : 1000 = 361.8735038 : 1000 = 0.36187 kg/mol

Cs2SO4: percent composition by element

• Cesium (Cs) = 265.8109038 : 361.8735038 * 100 = 73.454 %
