Question- Reference step 2 in the experiment guide (volume of your NaOH that will contain a number of moles of NaOH equal to 2.5 times the moles of aspirin you calculate to be in the tablet). State what volume of your NaOH solution you expect to use for this procedure. Using the standard three part format show the calculations you performed to arrive at this value. Hint: you will need to determine the theoretical moles of aspirin in a 325 mg tablet.
I am not able to get the correct answer please help me
Given 7.80 of butanoic acid and excess ethanol, how many grams of ethyl butyrate would be synthesized, assuming a complete 100 yield
What is the molarity of the concentration HCl (concentrated HCl is 37.2% by mass). How did you find this value? Using the molarity show that 7ml of concentrated HCl diluted to 2.0L with distilled water yields a solution that is about 0.10M HCl.
