Question

I equal portions o tretinoin gel (RET INA MICRO), 0.1% w/w and 0.04% w/w, are combined, what would be the resultant percentage strength?

Answer 1

Answer:

The resultant percentage strength is 0.07% w/w.

Question:

If equal portions of tretinoin gel (RETINA MICRO), 0.1% w/w and 0.04% w/w, are cembined, what would be the resultant percentage strength

Step-by-step explanation:

Since equal portions of the tretinoin gel (RETINA MICRO), 0.1% w/w and 0.04% w/w, are cembined, the resultant percentage strength would equals the average of the two percentage strength.

Average percentage strength Pav = (P1 + P2)/2

Pav = (0.1% w/w + 0.04%w/w)/2

Pav = (0.14% w/w)/2

Pav = 0.07% w/w

Therefore, the resultant percentage strength is 0.07% w/w.
