What amount of active ingredient,in grams (g),is present in 2 oz of hydrocortisone 4% cream?
Correct Answer: B
Rationale: To find the amount of active ingredient in grams in 2 oz of hydrocortisone 4% cream, first convert ounces to grams. There are approximately 28.35 grams in 1 oz, so 2 oz equals about 56.7 grams. A 4% concentration means that 4 grams of hydrocortisone are present per 100 grams of cream. Therefore, in 56.7 grams of cream, the amount of hydrocortisone is calculated as follows: (4 g/100 g) * 56.7 g = 2.268 g, which rounds to 2.4 g.
Option A (0.24) underestimates the concentration. Option C (24) and Option D (60) significantly overestimate the amount of active ingredient present.
