The equivalent weight of an element is 15 . It forms an acidic oxide; with potassium hydroxide it forms a salt isomorphous with $K_{2} SO_{4}$ . The atomic weight of the element would be

(Isomorphous salts have same molecular formula and same crystal structure)

As the acidic oxide forms a salt isomorphous with K₂SO₄, the oxide is similar to SO₃. Thus, the valency of the element in the oxide is the same as that of S in SO₃.
