Question

$12$ g of impure cyanogen undergoes hydrolysis by two different paths.
i. $(C N)_{2} + 4 H_{2} O \to (N H_{4})_{2} C_{2} O_{4}$
ii. $(C N)_{2} + 2 H_{2} O \to N H_{2} C O N H_{2}$
When $11.52$ g of pure ammonium carbonate $[(N H_{4})_{2} C O_{3}]$ was heated, the exact amount of urea was obtained. $20$ mL of $1.6 M$ acidic $K M n O_{4}$ is required to completely oxidise.
The percentage progress of the reaction in path (ii) is:
