Divalent metal chloride has a relative molecular weight of 135. Determine the metal, write down the formula for the hydroxide of this metal.

The formula for an unknown divalent metal chloride is MCl2, where M is an unknown divalent metal.

Let’s find the molar mass of the metal:

M (M) = M (MCl2) – 2 * M (Cl) = 135 – 2 * 35.5 = 64 (g / mol), which corresponds to the copper metal (Cu).

Copper (II) hydroxide formula: Cu (OH) 2.
