5. 25 cm3 of NH4Cl solution was poured into the apparatus for determining ammonium salts by distillation, then a concentrated NaOH solution was added. The released ammonia was absorbed with a 50 cm3 HCl solution, the titer of which was 0.003646 g/cm3. For titration of excess acid, 23.05 cm3 of NaOH solution with a titer of 0.004015 g/cm3 was used. What is the mass of ammonium chloride in the original solution?
