Question

Calculate the volume of buffer to which 500mL of 60 mM potassium chloride solution must be diluted to make a new concentration of 0.001M.

Answer 1

`30,000` mL

Step-by-step explanation:

Given -

Volume of buffer
`= 500` mL

Concentration of solution
`= 60` mM
`= 0.06`M

New concentration of the solution
`= 0.001`M

As we know

`C_1* V_1= C_2*V_2`

Where

`C_1, C_2` are the concentration of the solution before and after dilution.

And
`V_1, V_2` are the volume of solution before and after dilution.

Substituting the given values in above equation, we get -

`500* 0.06 = V_2* 0.001\\V_2 = (30)/(0.001) \\V_2 = 30,000`mL
