Calculate the mass of 56 liters of ammonia, a 10% aqueous solution of which is known in medicine

Calculate the mass of 56 liters of ammonia, a 10% aqueous solution of which is known in medicine as “ammonia”. What explains the use of ammonia in medicine?

Solution:
n (NH₃) = 56 / 22.4 = 2.5 mol
m (NH₃) = 17 * 2.5 = 42.5 g
m (p-pa) = 42.5 * 100/10 = 425
The fact that the smell of ammonia is very sharp and has an irritating effect on the respiratory system of a person, therefore, if a person loses consciousness and sniffs ammonia, he will come to his senses.
