Please break it down into steps. Simplify it, so that I understand. I have a problem with setting up thr problem & because theres two formulas for mass percent, I dont know what to use. Is there certain key words I need to look out for in order to know this ? a ) mass percent = mass of solute / mass of solution x 100% b ) mass percent = grams of solute / grams of solute + grams...

I'm doing a titration lab tomorrow and I am not sure what the
formulas are to calculate the moles of NaOH, the moles of
HCl, and the molarity of HCl.
The objective of this laboratory is to determine the molarity of
a hydrochloric acid solution using a known concentration of sodium
hydroxide as the titrant.
volume of HCl in flask: 25.00 mL
the net ionic equation for the reaction is:
H+(aq) + OH-(aq) --> H2O(l)

The purpose of the lab was to find the equilibrium constant of
the rxn of acetic acid and ethanol to yield ethyl acetate and
water. Hydrochloric acid is used as a catalyst. We have to
determine the equilibrium concentrations of all the species (water
included) present at equilibrium. In test tubes, different
concentrations of the equilibrium system were prepared then
titrated with NaOH to determine the total acid content of the
system at equilibrium. From this you will be able...
