How many ml of concentrated hydrochloric acid would be required to make 1 L of a 0.2 M solution? Assume that concentrated hydrochloric acid is 12.1 M

Respuesta :

Answer: The volume of concentrated hydrochloric acid required is 16.53 mL

Explanation:

To calculate the volume of concentrated solution, we use the equation:

[tex]M_1V_1=M_2V_2[/tex]

where,

[tex]M_1\text{ and }V_1[/tex] are the molarity and volume of the concentrated solution

[tex]M_2\text{ and }V_2[/tex] are the molarity and volume of diluted solution

We are given:

Conversion factor:  1 L = 1000 mL

[tex]M_1=12.1M\\V_1=?mL\\M_2=0.2M\\V_2=1L=1000mL[/tex]

Putting values in above equation, we get:

[tex]12.1\times V_1=0.2\times 1000\\\\V_1=16.53mL[/tex]

Hence, the volume of concentrated hydrochloric acid required is 16.53 mL
