) PABA refers to para-aminobenzoic acid which is used in some sunscreen formulations. If a 0.055 M solution of PABA has a pH of 2.96, determine the Ka of PABA. What kind of problem do you think thisis

of PABA is 0.000022

Explanation:

  cM              0             0

So dissociation constant will be:

Give c= 0.055 M and = ?

Putting in the values we get:

Thus of PABA is 0.000022

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).
