HC2H3O2 + NaOH ==> HOH + NaC2H3O2
Calculate mols NaOH from L x M = ??
Convert mols NaOH to mols HC2H3O2 using the coefficients in the balanced equation.
M acetic acid= mols/L.
Determine mols acetic acid in the 10 mL sample and from that grams acetic acid, then calculate percent from
[grams acetic acid/mass sample]*100
Post your work if you get stuck.
ok for part 2
moles of NaOH=L*M
.01*.5052=.005052 moles of NaOH
then moles of NaOH =moles of HC2H3O2 since 1-1 ratio from equation that makes .005052 moles of HC2H3O2 correct?
then M acetic acid=.005052 moles/.01688L which =2.9*10^-1 is that correct?
and for part 3 is it mols of acetic acid=.01688L*.5052M and then I'm kinda lost
You must have used 0.010 for L NaOH but the problem says volume NaOH is 16.88 mL.
Assume that your vinegar contained a small amount of citric acid (a triprotic acid).
Using the same experimental data, would you expect the molarity of this sample to be
the same as or different than a sample which contained only pure acetic acid?
What is the weight per volume percent (i.e. % density) of 0.5522 g acetic acid in the 10.00 mL sample?
