Question

What is the final concentration of a solution prepared by diluting 35.0 mL of 12.0 M HCl to a final volume of 1.20 L

Answer 1

Answer: The final concentration of a solution is 0.350 M

Step-by-step explanation:

According to the dilution law,

`C_1V_1=C_2V_2`

where,

`C_1` = concentration of concentrated acid solution = 12.0 M

`V_1` = volume of concentrated acid solution = 35.0 ml

`C_2` = concentration of diluted acid solution= ?

`V_2` = volume of another acid solution= 1.20 L = 1200 ml

( 1L=1000ml)

Putting in the values:

`12.0* 35.0=C_2* 1200`

`C_2=0.350M`

The final concentration of a solution prepared by diluting 35.0 mL of 12.0 M HCl to a final volume of 1.20 L is 0.350 M
