Respuesta :

The molar concentration of the ammonia is 2.96 M.

Explanation:

In titration the known concentrated acid or base solution is added to unknown concentration solution until a neutral point is formed.

In titrations the formula used is

Macid x V acid = Mbase x V base

The volume must be in litre.

From the question it can be found that HCl is used to neutralize household ammonia.

Volume of HCl is 18.5 ml which is [tex]\frac{18.5}{1000}[/tex] L

molarity of the HCl is given 0.8 M

Volume of the base NH3 is given 5ml which is [tex]\frac{5}{1000}[/tex] L

Using the formula given above

Macid x V acid = Mbase x V base

Putting the values in the equation:

0.8 x 0.0185 = Mbase x 0.005

Mbase =  [tex]\frac{0.8 x 0.0185}{0.005}[/tex]

  Mbase         = 2.96 M

Answer:

The molar concentration of the ammonia is 2.96 M.
