Some people have begun to formulate their own window-cleaning solutions using commonly available household chemicals. One formulation calls for mixing vinegar (dilute acetic acid, HC2H3O2) with water and a small amount of detergent. A commonly used recipe contains 12.8 g of acetic acid mixed with 333 g of water and 2.7 g of detergent. This recipe makes a total of 349 mL of solution. Required:
a. What is the mass percent of acetic acid in the window cleaner?
b. What is the molarity of acetic acid in the window cleaner?

Answer asap need 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.
