An oxide of metal `("at. wt. "= 112)` contain `12.5% O_(2)` by weight. The oxide was converted into chloride by treatment with `HCl` and electrolysed. Find the valency of metal.

An oxide of metal (at . Wt = 112) contains 12.5% of oxygen by weight. What is the valency of metal? What mass of the metal will be liberated when the oxide is converted to chloride with HCl and electrolysed using a current of 9.65 amp for a period of 30 min?
