For isomorphic salts the condition is that the valency of the replacing metal is same as that of the replaced in the former salt. In Mohr's salt the metal is Fe. In the new salt Fe is replaced by some other metal. So as per the required condition, valency of V in the new salt must be same as that of the valency of Fe in Mohr's salt, which is +2.

The oxidation state of V in the double salt isomorphous with Mohr's salt can be determined by analyzing the chemical formula and properties of the compound.

Double Salt
A double salt is a compound that contains two different cations and/or anions, which are held together by ionic bonds. These salts can be isomorphous, meaning they have the same crystal structure, but different chemical compositions.

Mohr's Salt
Mohr's salt, also known as ferrous ammonium sulfate, has the chemical formula (NH4)2Fe(SO4)2·6H2O. In this compound, the iron (Fe) ion has an oxidation state of +2.

Isomorphous Compound
The given compound is isomorphous with Mohr's salt, which means it has the same crystal structure. This implies that the cationic and anionic components of the compound are similar to those in Mohr's salt.

Oxidation State of V
To determine the oxidation state of vanadium (V) in the double salt, we need to consider the oxidation state of iron (Fe) in Mohr's salt.

The iron ion in Mohr's salt has an oxidation state of +2. Since the two compounds are isomorphous, the same cation is present in the double salt. Therefore, vanadium (V) in the double salt is also expected to have an oxidation state of +2 to maintain the same crystal structure.

Justification
In isomorphous compounds, the crystal structure is preserved, and the ions occupy the same positions within the lattice. This implies that the charge balance and coordination of the ions are similar. Since the oxidation state of iron (Fe) in Mohr's salt is +2, it is reasonable to assume that the vanadium (V) ion in the double salt would also have an oxidation state of +2 to maintain the same charge balance and coordination.

Therefore, the oxidation state of vanadium (V) in the double salt is +2, which is isomorphous with Mohr's salt.
