Molar and molecular weight of Ag2S

• Relative molecular weight of Ag2S: 247.8014
• Molar mass of Ag2S: 247.8014 g/mol (0.2478 kg/mol)

Calculation of the relative molecular and molar mass of Ag2S

• Mr[Ag2S] = Ar[Ag] * 2 + Ar[S] = 107.8682 * 2 + 32.065 = 247.8014
• Molar mass (kg/mol) = Mr[Ag2S] : 1000 = 247.8014 : 1000 = 0.2478 kg/mol

Ag2S: percent composition by element

• Silver (Ag) = 215.7364 : 247.8014 * 100 = 87.06 %
• Sulfur (S) = 32.065 : 247.8014 * 100 = 12.94 %
