A student was asked to determine the mass in grams of aspirin present in
0.2250 g of aspirin tablet. The
student placed the aspirin tablet in a
250 ml conical flask and added 50 ml
of 0.200 M NaOH. The excess NaOH
was then titrated with 0.250 M HCI,
the average HCl titer was 32.12 ml.
The mass in grams, of aspirin in
aspirin tablet is (M. W of aspirin
=180.158 g/mol). *
0.1770 g
O 0.048 g
O 0.0019 g
O None of the above​
