Step 1: Identify the Compound X from the Figure

From the structural diagram (image shows a compound with molar mass calculable from C, H, N composition), compound X with 0.42 g is used. The structure in the image is typically urea () or a similar nitrogen-containing compound. Molar mass of urea = 60 g/mol; it contains 2 nitrogen atoms.

Step 2: Calculate Moles of Compound X

Assuming the compound has molar mass M and n nitrogen atoms per molecule:

Step 3: Calculate Moles of N₂ Liberated
