Textbook Question
Chapter 5, Problem 53E
An NaOH(aq) solution cannot be made up to an exact concentration simply by weighing out the required mass of NaOH, because the NaOH is not pure.Also, water vapor condenses on the as it is being weighed. The solution must be standardized by titration. For this purpose, a 25.00 mL sample of an NaOH(aq) solution requires 28.34 mL of 0.1085 M HCI. What is the molarity of the NaOH(aq)?

Draw the Newman projection in staggered conformation for isoleucine by viewing the molecule along the
C-2-C-3 bond.
1. Edit the Newman projection on the canvas.
2. Replace the appropriate hydrogens with the appropriate -CH3 or other groups.
3. If you need to start over, Undo or choose a Newman projection from the Templates toolbar
(bottom).
Important: Never delete the hydrogen atoms or bonds directly attached to the template, and do not move
them by dragging or dropping them. That will break the projections structures. Only replace them!
