Answer: The final concentration of a solution is 0.350 M
Explanation:
According to the dilution law,
[tex]C_1V_1=C_2V_2[/tex]
where,
[tex]C_1[/tex] = concentration of concentrated acid solution = 12.0 M
[tex]V_1[/tex] = volume of concentrated acid solution = 35.0 ml
[tex]C_2[/tex] = concentration of diluted acid solution= ?
[tex]V_2[/tex] = volume of another acid solution= 1.20 L = 1200 ml
( 1L=1000ml)
Putting in the values:
[tex]12.0\times 35.0=C_2\times 1200[/tex]
[tex]C_2=0.350M[/tex]
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
