You have a solution of a standardized titrant of 0.01254 M and a sample that approximately has a molarity of 0.48 M. What dilution do you have to do to spend approximately 15 mL of titrant if you have 25 mL and 10 mL pipettes to take the diluted sample and value it ?

Question
You have a solution of a standardized titrant of 0.01254 M and a sample that approximately has a molarity of 0.48 M. What dilution do you have to do to spend approximately 15 mL of titrant if you have 25 mL and 10 mL pipettes to take the diluted sample and value it ?
Solution: With the 10 mL pipette, the sample should only be previously diluted 1:25, with the 25 mL one 1:64. Therefore, 10 mL of the sample can be taken and made up to 250 mL.
