Molar and molecular weight of Ag2C2

• Relative molecular weight of Ag2C2: 239.7578
• Molar mass of Ag2C2: 239.7578 g/mol (0.23976 kg/mol)

Calculation of the relative molecular and molar mass of Ag2C2

• Mr[Ag2C2] = Ar[Ag] * 2 + Ar[C] * 2 = 107.8682 * 2 + 12.0107 * 2 = 239.7578
• Molar mass (kg/mol) = Mr[Ag2C2] : 1000 = 239.7578 : 1000 = 0.23976 kg/mol

Ag2C2: percent composition by element

• Silver (Ag) = 215.7364 : 239.7578 * 100 = 89.981 %
• Carbon (C) = 24.0214 : 239.7578 * 100 = 10.019 %
