That depends on the density of the ointment. You did not provide enough information to answer the question. It's like asking "How much room does 10 pounds of stuff take up?" Well... are we talking cotton balls or marbles? 10 lbs of cotton balls takes up way more room than 10 lbs of marbles. You have to provide the density of the ointment in grams per cc. Then the answer can be calculated.
That is approximately 0.584 of a stick
To reduce the concentration of something in a substrate from 15 percent to 5 percent, you need to either decrease that something by three, or you need to triple the volume of the substrate. Assuming the coal tar ointment is based on vaseline, or that the density of each is comparable, you would add 40gm of vaseline to the 20gm of ointment, making a total mass of 60gm.
Ointment has two syllables: oint / ment.

It depends on the %mass of Sulfur in the ointment.
That is 5,000 cc
