Molar and molecular weight of Co(OH)2

• Molecular formula: Co(OH)2 or H2CoO2
• Relative molecular weight of Co(OH)2: 92.947875
• Molar mass of Co(OH)2: 92.947875 g/mol (0.09295 kg/mol)

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

• Mr[Co(OH)2] = Ar[H] * 2 + Ar[Co] + Ar[O] * 2 = 1.00794 * 2 + 58.933195 + 15.9994 * 2 = 92.947875
• Molar mass (kg/mol) = Mr[Co(OH)2] : 1000 = 92.947875 : 1000 = 0.09295 kg/mol

Co(OH)2: percent composition by element

• Hydrogen (H) = 2.01588 : 92.947875 * 100 = 2.169 %
• Cobalt (Co) = 58.933195 : 92.947875 * 100 = 63.405 %
• Oxygen (O) = 31.9988 : 92.947875 * 100 = 34.427 %
