Assuming that the lab procedure was conducted in an identical manner in all other respects, if a large quantity of vinegar had been taken initially for analysis, for example, a 50.0mL instead of 25.0 mL discuss briefly how each of the following would change.

Question

a. the moles of acetic acid in each titrated sample
b. the volume of naoh required to reach the phenolphthalein endpoint.
c. the molarity of the vinegar
d. the mass percent of acetic acid in vinegar.

Answer 1

You shouldn't find this that hard. Look at your original data. How did you determine mols initially.
Wouldn't you think that if you doubled the vinegar at the start you would have double the mols?
b. Wouldn't you think it you took x mL to tirate the 25 that it would take 2x mL to titrate 50?
c. Wouldn't you think the M would be the same. M = mol/L. You double mols and double L as in 2*mol/2*L; M stays the same.
etc.
