The substance is also lacking NH3; without NH3, how can there be an ionization equilibrium for ammonia? 20% ammonia can also be defined in this way; it’s also possible to define NH3 as 20%. However, molal concentration is rarely used for solutions – it’s more common to consider the mass composition. Don’t say that the chemical name of “20” is NH3.
This is the Aspen template for the application, nh3h2o.bkp. Indeed, “20” represents NH3. When opening a template for the first time, it’s necessary to assign a name to it; I didn’t know why at the time and just typed 20 randomly, which corresponds to NH3. Now I understand it better. Thank you!
Also, may I ask which property values should be used when simulating the pyrolysis of urea using Aspen?

Urea seems to be able to use amine as a template
