What is the logical sequence to calculate a liquid's concentration in a pharmacy?

• A. volume (ml) is divided by total weight
• B. weight (gm) is divided by volume (ml)
• C. total weight is subtracted from volume (ml)
• D. volume (ml) is multiplied by concentration factor

Answer: (B)

To calculate a liquid's concentration, the logical sequence involves dividing the weight of the solute (in grams) by the volume of the solution (in milliliters). This method yields the concentration usually expressed in grams per milliliter (g/ml) or another appropriate unit. Understanding the key components of this process is crucial: the weight represents the amount of solute present, while the volume indicates the total space that the solute occupies within the solution. The ratio of these two components effectively describes how concentrated the solution is. Thus, this approach is fundamental in pharmacy, as it allows technicians to determine the potency, dosage, or other critical parameters of medicinal preparations.
