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
sineoko [7]

Answer: The final concentration of a solution is 0.350 M

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\times 35.0=C_2\times 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
