Step-by-step explanation:
Ammonia will dissolve in water to produce a basic solution of ammonium hydroxide.
NH₃ + H₂O ---> NH₄OH
Ammonium hydroxide in solution will split into its ions.
NH₄OH ---> NH₄⁺ + OH⁻
According to the problem when 34 g of of ammonia are dissolved 92 kJ of energy are absorbed.
34 g of NH₃ : 92 kJ of energy
We can use that relationship to find the mass of ammonia that is dissolved when 184 kJ is absorbed.
mass of NH₃ = 184 kJ * 34 g/(92 kJ)
mass of NH₃ = 68 g
Answer:
NH₃ + H₂O ---> NH₄OH NH₄OH ---> NH₄⁺ + OH⁻
68 g of ammonia are dissolved.
