60ml of mixture of equal volumes of Cl_(2) and an oxide of chloine, i.e., Cl_(2)O_(n) was heated and then cooled back to the original temperature. The resulting gas mixture was found to have volume of 75ml . On treatment with KOH solution, the volume contracted to 15ml . Assume that all measurements are made at the same temperature and pressure. Deduce the value of n in Cl_(2)O_(n) . The oxide of Cl_(2) n heating decomposes quantiatively to O_(2) and Cl_(2) .
