A typical sample of vinegar has a pH of 3.0. Assuming that vinegar is only an aqueous solution of acetic acid (Ka=1.8x10^-5), calculate the concentration of acetic acid in vinegar.

Concentration of acetic acid in vinegar is 0.06 M

Explanation:

     cM              0             0

So dissociation constant will be:

Putting in the values we get:

Thus concentration of acetic acid in vinegar is 0.06 M

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )

a is the correct answer
