Molar and molecular weight of Co(OH)3

• Relative molecular weight of Co(OH)3: 109.955215
• Molar mass of Co(OH)3: 109.955215 g/mol (0.10996 kg/mol)

Calculation of the relative molecular and molar mass of Co(OH)3

• Mr[Co(OH)3] = Ar[Co] + Ar[O] * 3 + Ar[H] * 3 = 58.933195 + 15.9994 * 3 + 1.00794 * 3 = 109.955215
• Molar mass (kg/mol) = Mr[Co(OH)3] : 1000 = 109.955215 : 1000 = 0.10996 kg/mol

Co(OH)3: percent composition by element

• Cobalt (Co) = 58.933195 : 109.955215 * 100 = 53.597 %
• Oxygen (O) = 47.9982 : 109.955215 * 100 = 43.652 %
• Hydrogen (H) = 3.02382 : 109.955215 * 100 = 2.75 %
