How many cubic meters are required to convert 1 ton of liquid ammonia into gaseous ammonia? Urgent!!!

Sea friends: How many cubic meters are there in 1 ton of liquid ammonia when converted to gaseous ammonia? Urgent!!! How do I perform this unit conversion?
This should be related to the temperature and pressure of gaseous ammonia. First, calculate the number of moles in 1 ton of liquid ammonia, and then use the ideal gas law PV=nRT to approximately determine the volume at the corresponding temperature and pressure.
1000/17.03*22.4=1315 Nm3; the standard volume in cubic meters for any gas can be calculated as: kg/molar mass*22.4 (Nm3/kmol).
This formula doesn’t seem to be the same as PV=nRT from the second floor, right??? Thank you!!1
Reply to 1# sd435235633: First, it is necessary to know the temperature and pressure at which the ammonia is converted into a gas. What was said above is basically correct, as those calculations are based on the assumption of an ideal gas. If we want to determine the actual volume of gaseous ammonia at a certain temperature and pressure, we must use the actual temperature and pressure values. By referring to the nitrogen fertilizer process manual, we can find the critical temperature and critical pressure of gaseous ammonia, calculate the comparative temperature and comparative pressure, and determine the compressor factor; only then can we compute the actual volume at that specific temperature and pressure.
Reply to 4# sd435235633: It’s actually the same thing, as he calculated it based on an ideal gas under standard conditions, that is, a volume with one atmosphere of pressure and zero degrees as the standard.
To calculate the value under standard conditions, use the general formula: 1000 divided by the molecular weight, then multiplied by 22.4. If the temperature and pressure are different, the calculation must be adjusted accordingly.
Ammonia: 22.1 m3/mol; density of liquid ammonia at 20 degrees: 0.610258 g/L
It is related to temperature and pressure; just look up the density of gaseous ammonia at the desired temperature or pressure, and that’s it
The density of 100% ammonia solution is 0.613 g/cm3 at 15°C, while the density of 95% ammonia solution is 0.642 g/cm3 at 15°C.
The one on the 5th floor is more reliable; under standard conditions, there is an issue related to the critical vapor pressure, and if the temperature and pressure change, this issue cannot be explained simply in a few words.
