The mass percentage of hydrochloric acid within a solution is 28.00%28.00% . Given that the density of this solution is 1.1411.141 g/mL, find the molarity of the solution.

Respuesta :

Answer:

8.76M

Explanation:

Given that

Mass from the density = 1141g

According to the given situation the computation of molarity of the solution is shown below:-

we will took HCL solution which is 1000mL

HCl = 28% by mass

So,

Mass of HCl in 1-litre solution is

[tex]= \frac{28}{100} \times 1141[/tex]

Which gives the result of molar mass HCI is

= 319.48g /mol

Now,

Molarity is

[tex]= \frac{319.48}{36.45}[/tex]

Which gives results of molarity is

= 8.76M
