A solution of acetic acid (CH3COOH and water that is 75.% acetic acid by mass is boiling at 105.2 °C. The vapor is collected and cooled until condenses to form a new solution. Calculate the percent by mass of acetic acid in the new solution. Here's some data you may need: ormal vapor pressure density boiling point at 105.2 °C 118, °C 593. torn 1.1 mL acetic acid 1 00 910. torr 100. °C water ml Be sure your answer has the correct number of significant digits. Note for advanced students: you may assume the solution and vapor above it are ideal 10 X

Which piece of equipment would me most useful for measuring the volume of some water? a. pan balance b. graduated cylinder c. tweezers d. flask quick

How many miles of water are produced if 5.43 mol pbo2 are consumed

Answer asap need to be answered by wednesday morning explain how a buffer works, using an ethanoic acid / sodium ethanoate system including how the system resists changes in ph upon addition of a small amount of base and upon addition of a small amount of acid respectively. include the following calculations in your i. calculate the ph of a solution made by mixing 25cm3 0.1m ch3cooh and 40cm3 0.1m ch3coo-na+. [ka = 1.74 x 10-5 m] ii. calculate the ph following the addition of a 10cm3 portion of 0.08 m naoh to 500cm3 of this buffer solution. iii. calculate the ph following the addition of a 10cm3 portion of 0.08 m hcl to 200cm3 of the original buffer solution.
