Molar and molecular weight of Cs2S

• Relative molecular weight of Cs2S: 297.8759038
• Molar mass of Cs2S: 297.8759038 g/mol (0.29788 kg/mol)

Calculation of the relative molecular and molar mass of Cs2S

• Mr[Cs2S] = Ar[Cs] * 2 + Ar[S] = 132.9054519 * 2 + 32.065 = 297.8759038
• Molar mass (kg/mol) = Mr[Cs2S] : 1000 = 297.8759038 : 1000 = 0.29788 kg/mol

Cs2S: percent composition by element

• Cesium (Cs) = 265.8109038 : 297.8759038 * 100 = 89.235 %
• Sulfur (S) = 32.065 : 297.8759038 * 100 = 10.765 %
