Household ammonia used for cleaning contains about 10 g (two significant figures) of NH3 in 100 mL (two significant figures) of solution. What is the molarity of the NH3 in the solution?
1 answer:
Answer:
11.44
Explanation:
= Base ionization constant of ammonia =
m = Mass of ammonia = 5 g
V = Volume of ammonia = 709 mL =
M = Molar mass of ammonia = 17.03 g/mol
Molaritiy of ammonia
We have the relation
The pH of the solution is 11.44.
