Ontario Registered Pharmacy Technician (RphT) Practice Exam

The correct answer is C. 50g. This is because the percentage listed (2%) represents the amount of active ingredient in relation to the total weight of the ointment. So if 2% of the ointment is the active ingredient, that means the remaining 98% is made up of other ingredients and fillers. Therefore, to get 1g of the active ingredient, we would need 50g of the ointment since 2% of 50g is equal to 1g. The other options are incorrect because A and D are too high and B is too low. Make sure to pay attention to the given percentage and how it relates to the total weight when solving this type of problem.
