Let's say that you were given the following
problem:
a gas that exerts a pressure of 151 mm hg in a
container with a volume of _ l will exert a
pressure of 166 mm hg when transferred to a
container with a volume of 0.532 l.
answer
let's begin by assigning our variables. let's say
that p1 = 151 mm hg. what is v2?
a. 166 mm hgb. 0.532 l
c. unknown

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.
