Title: NH4NO3 + H20 Thermal Expansion Change
Post by: mrxovoc on December 31, 2021, 02:17:33 PM

How do I calculate the change in volume from a 93% NH4NO3 and 7% H2O solution with a Delta T of 30 degrees Celsius 25 to -5?

In general: no way to do it without some additional, experimental data about thermal expansion of such solution.

93% NH4NO3 and 7% H2O solution

This exceeds the solubility limit.
