Molar and molecular weight of Co(CN)2

• Molecular formula: Co(CN)2 or C2CoN2
• Relative molecular weight of Co(CN)2: 110.967995
• Molar mass of Co(CN)2: 110.967995 g/mol (0.11097 kg/mol)

Calculation of the relative molecular and molar mass of Co(CN)2

• Mr[Co(CN)2] = Ar[C] * 2 + Ar[Co] + Ar[N] * 2 = 12.0107 * 2 + 58.933195 + 14.0067 * 2 = 110.967995
• Molar mass (kg/mol) = Mr[Co(CN)2] : 1000 = 110.967995 : 1000 = 0.11097 kg/mol
