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​

For the following dehydrohalogenation (e2) reaction, draw the zaitsev product(s) resulting from elimination involving c3–c4 (i.e., the carbon atoms depicted with stereobonds). show the product stereochemistry clearly. if there is more than one organic product, both products may be drawn in the same box. ignore elimination involving c3 or c4 and any carbon atom other than c4 or c3.
