Chemistry
Carbon dioxide dissolves in water to form carbonic acid, which is primarily dissolved CO2. Dissolved CO2 satisfies the equilibrium equation CO2(g) <-> CO2(aq) K=0.032 The acid dissociation constants listed in most standard reference texts for carbonic acid actually apply...

How can I rank these substrates from fastest to slowest reacting? In an SN2 reaction with NaI-Acetone? Based on theory alone? benzyl chloride n-butyl bromide n-butyl chloride sec-butyl chloride tert-butyl chloride

I also have the density of the distillate. I don't know what the initial and final purity of the mixes is, we were just told we were distilling "unpurified" acetone.

Chemistry
Information: -mass (of both unpurified and purified acetone) -volume -boiling point temperature (not sure if that's relevant)

Chemistry
Yes, I have the volume of the purified acetone

Chemistry
I know the initial volume of unpurified acetone (before distillation) and the final volume of acetone (after distillation)

Chemistry
I did a simple distillation and a fractional distillation to purify acetone. How do I determine the concentration of acetone? (Instructions say this is not a simple M=mol/L calculation). My guess was to divide the volume of purified acetone by the volume of unpurified acetone...
