Vinegar is a dilute solution ethanoic acid in water (see the question above for the structure of ethanoic acid). in order to test the strength of a vinegar, a 10.00 gram sample was titrated with sodium hydroxide (0.1001 mole/kg of solution). the mass of the. burette before the titration is 131.44 g and upon reaching the endpoint the burette weighted 48.11 g. how many moles of acetic acid are in the sample?
