17. The pain reliever, aspirin, is the cornpound acetylsalicylic acid, C.Hg04. a) What is the molar...
Aspirin is acetylsalicylic acid (ASA) ( C9H8O4). It reacts with NaOH ( a base) to produce salt (sodium acetylate) and water. Both Aspirin and NaOH react in 1:1 molar ratio, as C9H8O4 + NaOH → NaC9H7O4 + H2O So, moles of NaOH = moles of ASA Or, mmol of of NaOH = mmole of ASA ; mmol is milli mol and mmole of NaOH = Molarity of NaOH * Volume of naOH used (in ml) = (0.1177 M) *...
A typical aspirin tablet contains 324 mg of acetylsalicylic acid (C9H8O4), a monoprotic acid having a Ka = 3.0 x 10-4. If you dissolve two aspirin tablets in 300. mL of water, what is the pH of the solution acetylsalicylic acid? A typical aspirin tablet contains 324 mg of acetylsalicylic acid (C9H8O4), a monoprotic acid having a Ka = 3.0 x 10-4. If you dissolve two aspirin tablets in 300. mL of water, what is the percent dissociation of the...
10. Calculate the theoretical yield of aspirin using 4.00 g of salicylic acid as the starting material. Assume acetic anhydride is in excess. (Hint: from the mass of salicylic acid acid use, how many moles of salycilic acid are present intitially? What is the salycilic acid : acetylsalicylic acid molar ratio? How many moles of acetylsalicylic acid are formed assuming 100% yield? Based on this abount of moles, how many grams of acetylsalicylic acid are formed? (this is the theoretical...
Please show me how to do e & f. Thanks The painkiller commonly known as aspirin is the chemical compound acetylsalicylic acid, of molecular formula C_2H_2O_4. In 325 mg of aspirin: a) How many motes of acetylsalicylic acid are present? b) How many acetylsalicylic acid molecules are present? c) How many carton atoms are present? d) What is the mass (in milligrams) of just the oxygen atoms? e) What is the volume of the sample in cm^3? (density = 1.40...
Aspirin, which is acetylsalicylic acid, was the first NSAID use to alleviate pain and fever. If a solution of aspirin has an [OH-] = 5.8 x 10-12 M, what is the [H3O+], of solution?
3a) The solubility of Aspirin (acetylsalicylic acid) at 25C is 3.0 mg/mL of water. Calculate the molar concentration (M) of acetylsalicylic acid in solution at this temperature. What density assumption can help you in solving this problem? b) The acid dissociation constant, Ka for acetylsalicylic acid is 3.0 x 10 -4. calculate the pH of this solution.
Using your data, calculate the moles and mass of acetylsalicylic acid in each tablet (molar mass = 180.16 g/mol). Data Concentration of NaOH 107 M Solutions Mass of Aspirin Tablet #11 Mass of Aspirin Tablet #21 Volume of NaOH mixed with Tablet #1 | Volume of NaOH mixed with tablet #2 Value .37 .36 50 mL 50 mL Standardization of HCl Trial #1 Value Mass of Na2CO3 .070 a Initial Volume of HCI in burettel 2.20 mL Volume of HCl...
II. Digestion of Acetylsalicylic acid(standard and tablet) with NaOH . Digestion of Acetylsalicylic Acid Standard to Prepare Stock Solution: Obtain ca. 0.1 g dried acetylsalicylic acid (MM = 180.16 g/mol), accurately weighed, and quantitatively transfer to a 125-ml Erlenmeyer flask. Add 5 ml 1.0 M NaOH and heat mixture to boiling on a hot plate. This will hydrolyze the acetylsalicylic acid to sodium salicylate. If necessary, rinse down the walls of the Erlenmeyer with DI water to ensure complete hydrolysis...
