17. A solution is prepared by dissolving 5.00 g of aspirin, C9H3O4, in 215 g of chloroform, has a boiling point that is elevated by AT = 0.47 °C over that of pure chloroform. What is the value of the boiling point elevation constant for chloroform? 18. What osmotic pressure in atmospheres would you expect for each of the following solutions? a) 5.00 g of NaCl in 350.0 mL of aqueous solution at 50 °C
Aspirin (acetylsalicylic acid, C9H8O4) is a weak monoprotic acid. To determine its acid-dissociation constant, a student dissolved 2.00 g of aspirin in 0.600 L of water and measured the pH. What was the Ka value calculated by the student if the pH of the solution was 2.62?
The pKa of aspirin (a.k.a. acetylsalicylic acid) is 3.40. Use the Henderson-Hasselbach equation to calculate the ratio of acetylsalicylate (i.e., the conjugate base of aspirin) to aspirin in the stomach at pH = 1.75.

What % of acetylsalicylic acid dissociates to make H3O+1 ions in water? Compare aspirin dissociation to acids like KHP and HCl. You will need to do a little bit of research and look into the acid dissociation constant, abbreviated by the symbol Ka. For context and clarity, you will want to define acid/base strength and acid dissociation constant.
