Molar and molecular weight of CoI2

• Relative molecular weight of CoI2: 312.742135
• Molar mass of CoI2: 312.742135 g/mol (0.31274 kg/mol)

Calculation of the relative molecular and molar mass of CoI2

• Mr[CoI2] = Ar[Co] + Ar[I] * 2 = 58.933195 + 126.90447 * 2 = 312.742135
• Molar mass (kg/mol) = Mr[CoI2] : 1000 = 312.742135 : 1000 = 0.31274 kg/mol

CoI2: percent composition by element

• Cobalt (Co) = 58.933195 : 312.742135 * 100 = 18.844 %
• Iodine (I) = 253.80894 : 312.742135 * 100 = 81.156 %
