A buffer that contains 0.132 M acid, HY, and 0.204 M of its conjugate base, Y, has a pH of 8.87. What is the pH after 0.0017 mol of Ba(OH), is added to 0.374 L of this solution? Be sure your answer has the correct number of significant figures. pH= C

The density of trifluoroacetic acid vapor was determined at 118.1 °C and 468.5 torr, and found to be 2.784 g/L. Calculate K, for the association of the acid. 0-H...O 2CF,CO,H(g) = CF;C CF,C(g) O----H-O

What is the molarity of 25.79 g of Cl2 dissolved in 500 mL of solution. (Hint: convert from grams to moles)

An analytical chemist is titrating 205.5 mL of a 0.5600M solution of hydrazoic acid (HN3) with a 1.100M solution of NaOH. The pK of hydrazoic acid is 4.72. Calculate the pH of the acid solution after the chemist has added 111.8 mL of the NaOH solution to it. Note for advanced students: you may assume the final volume equals the initial volume of the solution plus the volume of NaOH solution added. Round your answer to 2 decimal places. pH = 0

The pOH of a basic solution is 3.75. What is [H⁺]?

The molecular weight of glucose is 180.16 g/mol. Say you want to make 100 ml of a 0.6M solution of glucose. How much glucose and water should you use? Show your calculations for how you would make this solution.
