An element X forms two oxides. Formula of the first oxide is XO2. The first oxide contains 50% of oxygen. If the second oxide contains 60% oxygen, The formula of the second oxide

First Oxide = XO2% by Wt of Oxygen = 50% by Wt of X = 50%1 mole XO2 contains 1 gram atom of X and 2 gram atoms of Oxygenthe Wt % of oxygen = Wt % of Xwt of 2 gram atoms of y' = Wt of one gram atom of 'X'GAW of X = 32gSecond oxide contains 60% by Wt of OxygenFormula of second oxide = XO3
