Question

You will perform several calculations with the date you obtain inthe Titrations lab. Below is an exercise to help prepare you.
a. If your titration solution is 0.434 M in NaOH, and the endpoint occursat 13.30 mL of titrant, how manymmol of NaOH are required to reach the endpoint?
mmolNaOH
b. How many mmol of acetic acid(HC2H3O2) are required to reactwith the NaOH?
mmolHC2H3O2
c. How many grams of acetic acid is this?
gramsHC2H3O2
d. If the mass of analyte is 10.450 grams, what is the mass % of acetic acidin the analyte?
