Molar and molecular weight of Ag2SeO4

• Relative molecular weight of Ag2SeO4: 358.694
• Molar mass of Ag2SeO4: 358.694 g/mol (0.35869 kg/mol)

Calculation of the relative molecular and molar mass of Ag2SeO4

• Mr[Ag2SeO4] = Ar[Ag] * 2 + Ar[Se] + Ar[O] * 4 = 107.8682 * 2 + 78.96 + 15.9994 * 4 = 358.694
• Molar mass (kg/mol) = Mr[Ag2SeO4] : 1000 = 358.694 : 1000 = 0.35869 kg/mol
