The emf of a cell formed by dipping two electrons of metal (M) in two solution of its salt in which the concentration of metal ion `(M^(n+)` is 0.1 M and 0.001 M was observed to be 0.03 volt at `25^(@)C`. What is the valency of the metal ion if the two half cells are connected using salt bridge?   [Given: 2.303 (RT)/F = 0.06]
