Molar and molecular weight of Ag2SO4

• Molecular formula: Ag2SO4 or Ag2O4S
• Relative molecular weight of Ag2SO4: 311.799
• Molar mass of Ag2SO4: 311.799 g/mol (0.3118 kg/mol)

Calculation of the relative molecular and molar mass of Ag2SO4

• Mr[Ag2SO4] = Ar[Ag] * 2 + Ar[O] * 4 + Ar[S] = 107.8682 * 2 + 15.9994 * 4 + 32.065 = 311.799
• Molar mass (kg/mol) = Mr[Ag2SO4] : 1000 = 311.799 : 1000 = 0.3118 kg/mol

Ag2SO4: percent composition by element

• Silver (Ag) = 215.7364 : 311.799 * 100 = 69.191 %
• Oxygen (O) = 63.9976 : 311.799 * 100 = 20.525 %
• Sulfur (S) = 32.065 : 311.799 * 100 = 10.284 %
