(a) Some potassium permanganate was heated in the test tube. After collecting one litre of oxygen at room temperature, it was found that the test tube had undergone a loss in mass of $1.32 g$. If one litre of hydrogen under the same conditions of temperature and pressure has a mass of $0.0825 g$, calculate the relative molecular mass of oxygen.
(b) Given that the molecular mass of potassium permanganate is 158 . What volume of oxygen (measured at room temperature) would be obtained by the complete decomposition of $15.8 g$ of potassium permanganate? (Molar volume at room temperature is 24 litres)
