Question

Determine valency of M in M(OH)2​

Answer 1

Answer:

M(OH)2, and we know that 32.8% of the mass is oxygen, so using the g-mol masses of oxygen and hydrogen, we know that 32/(M+32+2) = 0.328 or 32/0.328 ...

Answer 2

Here we have to find the valency of the 'M' in the compound M(OH)₂

• Now, here in the compound M(OH)₂, one hydroxyl molecule gains one electron from the metal atom in order to form a bond.

• Here two hydroxyl molecules are forming the bond with the metal atom.

• So, the metal atom loses its two electrons to the hydroxyl molecule.

• Therefore the valency of the center atom 'M' will be 2.
