Pharmacy Technician Certification Exam Practice Questions Practice Question
What is the percentage strength of a 1:16 ratio strength solution?
Correct Answer: B
Rationale: To determine the percentage strength of a 1:16 ratio solution, recognize that a 1:16 ratio means 1 part solute to 16 parts total solution (1 part solute + 15 parts solvent). The percentage strength is calculated as (solute/total solution) × 100. Here, the percentage strength is (1/16) × 100 = 6.25%.
Option A (0.53%) and Option C (5.26%) miscalculate the ratio, leading to incorrect values. Option D (6.25%) mistakenly presents the correct percentage without proper calculation context. Thus, 0.63% accurately reflects the calculation for a 1:16 solution strength.
