Does someone mind helping me with this question? I'd really appreciate it.
Thank you!
1. Assume that you have 1, 2, 5, and 10 mL pipets and a 25 mL volumetric flask. Describe in detail how you would prepare a solution with a concentration near o.100 M from a 0.650 M stock solution. Calculate the final concentration of the diluted solution (t won't be exactly 0.100 M). It should be within 10% of 0.100 M. (Please see the Lab skills for the accuracy on volumetric pipets and flasks.)
