You wish to make a 0.341 M hydroiodic acid solution from a stock solution of 6.00 M hydroiodic acid. How much concentrated acid must you add to obtain a total volume of 75.0 mL of the dilute solution?

Answer: The volume of concentrated acid added will be 4.26 ml

Step-by-step explanation:

The expression used will be dilution law:


M_1V_1=M_2V_2

where,


M_1 = concentration of stock
HI = 6.00 M


M_2 = concentration of resulting
HI = 0.341 M


V_1 = volume of stock
HI = ?


V_2 = volume of resulting
Hl = 75.0 ml

Now put all the given values in the above law, we get the volume of stock
Hl added


6.00* V_1=0.341* 75.0

By solving the terms, we get :


V_1=4.26ml

Therefore, the volume of concentrated acid added will be 4.26 ml
