1.	A 1 g sample of KClO3 was heated under such conditions that a part of it decomposed according to the equation.(i) 2KClO3→2KCl+3O2And the remaining underwent change according to the equation. (ii) 4KClO3→3KClO4+KClIf the amount of oxygen evolved was 146.8 mL at NTP, calculate the percentage by weight of KClO4 in the residue.
Answer» A 1 g sample of $K C l O_{3}$ was heated under such conditions that a part of it decomposed according to the equation. $(i) 2 K C l O_{3} \to 2 K C l + 3 O_{2}$ And the remaining underwent change according to the equation. $(i i) 4 K C l O_{3} \to 3 K C l O_{4} + K C l$ If the amount of oxygen evolved was 146.8 mL at NTP, calculate the percentage by weight of $K C l O_{4}$ in the residue.
