20.0 mL of .115 M acetic acid was mixed with 10mL of .115 M NaOH and 10 mL of H20. Assume the reaction goes to completion. How many moles of acetate ions are formed and the number of moles of excess acetic acid left over? Also what is the molar concentrations for those two. The solution volumes are additive. Thank you so much I can't figure this out and I've been looking at it for 2 hours. I need it for my lab report.
