Atomic masses: H-1.008, F 19.00 (a) If it takes 38.5 s for a given amount of CO(g) to effuse from a chamber, how long, expressed in seconds, will it take the same amount of Ne(g) gas to effuse from this chamber under the same...
You will be using a mixture of 5:1:4 volume ratio of butanol, glacial acetic acid (pure acetic acid), and water in this lab. Assume that butanol is the same as water in terms of a pH calculation. The density of acetic acid is 1.05 g/ml. The molecular weight of acetic acid is 60.05 g/mol. The Ka of acetic acid HAc is 1.8*10^-5. You can make the assumption that [H+] = [Ac-] << [HAc] here. What is the pH of this...

colligative properties: freezing point depression. Gen chem 2 HINKI Acetic acid is known as a weak acid (electrolyte) when it is dissolved in water. A solution was prepared by dissolving acetic acid in cyclohexane to yield a concentration of 1.0 molukg. The freezing point depression of the solution was determined to be 13.2 °C. What is the van't Hoff factor for acetic acid dissolved in cyclohexane? Is acetic acid an electrolyte when it is dissolved in cyclohexane? Explain. Kre20 °C/m...
