Molar Mass of your Unknown Acid.
Unknown acid code: ______________
1.
For each titration
(i.e. include the pH titration), calculate the number of moles
of base required
to neutralize the acid sample. Show
all calculations including units and the correct
number of
significant figures. (Do not
use C1V1 = C2V2.).
(0.5 marks)
2.
For each titration,

stoichiometric ratio and units in
your calculations. (0.5 marks)
3.
Reported value for the molar mass
of your unknown acid (accuracy). (2.0 marks)
