What volume of water would be added to 16.5 mL of a 0.0813 M solution of sodium borate in order to get a 0.0200 M solution?
To solve this we'll need to apply the equation
Solve the equation for V2
Please note the question asks you to find the volume that must be added. You'll need to subtract 16.5mL from 67.1 to find the answer of
Here is a video which discusses how to perform dilution calculations.
