The molecular formula of copper acetate depends on whether it's the copper(I) acetate or copper(II) acetate.

Here's a breakdown:

* Copper(I) acetate: CuCH₃COO

* Copper(II) acetate: Cu(CH₃COO)₂

Explanation:

* Copper(I) has a +1 charge (Cu⁺).

* Copper(II) has a +2 charge (Cu²⁺).

* Acetate has a -1 charge (CH₃COO⁻).

To balance the charges in the compound, you need:

* One copper(I) ion (Cu⁺) and one acetate ion (CH₃COO⁻) to form CuCH₃COO.

* One copper(II) ion (Cu²⁺) and two acetate ions (CH₃COO⁻) to form Cu(CH₃COO)₂.

Note: Copper(II) acetate is much more common than copper(I) acetate.
