What is the molar mass of Cu(OH)2?

Answer

M(Cu(OH)2) =
97.560 g/mol

Atomic weights: IUPAC standard values (CIAAW, 2024).

Cu(OH)2 = Cu + 2 × (O + H) → Cu 1, O 2, H 2

Contribution of each element
Element Atoms, n Atomic weight, A n × A, g/mol Mass fraction, w

Ooxygen215.99931.998 w ≈ 32.80%
Hhydrogen21.00802.0160 w ≈ 2.07%
Σ = 97.560 g/mol w = 100%

Each fraction is rounded on its own, so the printed ones add up to 100.01%; unrounded, they make exactly 100%.
