Ammonia solution titration issue?

1dNH3 = 1/20ηNH3 = 0.85 grams of NH3 per liter of solution; χNH3 (grams of NH3 per gram of solution) = 17×ηNH3/γL = 0.85dNH3/γL. Here, dNH3 represents the concentration titration of ammonia water, ηNH3 is the equivalent concentration of ammonia water, χNH3 denotes the weight concentration of ammonia water, and γL is the specific gravity of the carbonated solution, expressed in kg/m³ or g/L

Titer (abbreviated as tt or Ti) is a concentration expressed in units that are 1/20 of the molar concentration (mol/L); in other words, 1 mol/L is equivalent to 20 tt. To convert the titer to g/L, the value is calculated using the following formula； (Titer × molecular weight) / (20 × valence)

Titer was a common method used in the past to indicate the ammonia concentration in solutions. 1 titer = 1/20 of the equivalent concentration; this is equal to 1/20 × 17 grams of ammonia per liter, which equals 0.85 grams of ammonia per liter. The conversion formula is as follows: Percentage concentration = Titer of ammonia solution × 0.85 / Density (weight) of the solution × 100% = 0.85 × Titer of ammonia solution / Weight of the solution

Knowledge of ammonia solution titration: In nitrogen fertilizer manufacturers, the concentration of ammonia solutions is generally expressed in terms of titration. Based on theoretical calculations, the formula for converting 1 tt of ammonia solution into a mass concentration (%) is as follows: 17/(20×1000)×100%. Here, 17 represents the molecular weight of ammonia; 20 indicates that every 20 tt of ammonia solution corresponds to 1 equivalent concentration; the unit for equivalent concentration is moles per liter; and 1000 means that 1 liter of ammonia solution is approximately equal to 1000 grams. Once the mass percentage is known, it’s simple to convert ammonia solution into liquid ammonia. However, there are losses in the actual process, so the conversion is on a discounted basis. For example: To find out how many tons of liquid ammonia are equivalent to 1 ton of ammonia solution with a concentration of 120 tt, the theoretical calculation is as follows: 120x17/(20x1000)x100%x1=0.102 (tons)
