Ammonium carbamate when heated to `473 K` gives a mixture of `NH_(3)` and `CO_(2)` vapour with a density of `13`. Find the degree of dissociation of ammonium carbamate.

Explanation

To find the degree of dissociation of ammonium carbamate when heated to 473 K, we can follow these steps:

### Step 1: Write the dissociation reaction
Ammonium carbamate (NH2COONH4) dissociates into ammonia (NH3) and carbon dioxide (CO2):
\[ \text{NH}_2\text{COONH}_4 \rightleftharpoons 2 \text{NH}_3 + \text{CO}_2 \]

### Step 2: Determine the initial and final moles
Initially, we have 1 mole of ammonium carbamate. Upon dissociation, it produces:
