Given:

12.0 M HCl

2.0 liters of a 3.0 M HCl

Required:

volume of concentrated hydrochloric acid

Solution:

M1V1 = M2V2

(12.0 M HCl)V1 = (3.0 M HCl)( 2.0 liters)

V1 = (3.0 M HCl)( 2.0 liters)/ (12.0 M HCl)

V1 = 0.5 liters

<u>Answer:</u> The volume of concentrated HCl solution is 0.5 L

<u>Explanation:</u>

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

M_1V_1=M_2V_2

where,

M_1\text{ and }V_1 = molarity and volume of the concentrated HCl solution

M_2\text{ and }V_2 = Molarity and volume of the diluted HCl solution

We are given:

M_1=12M\\V_1=?L\\M_2=3M\\V_2=2L

Putting values in above equation:

12M\times V_1=3M\times 2L\\\\V_1=0.5L

Hence, the volume of concentrated HCl solution is 0.5 L
