The notation 5% in a solution typically refers to which of the following?

The notation of 5% in a solution commonly means that there are 5 grams of solute in 100 milliliters (cc) of solution. This is a standard way to express concentration, indicating that if the total volume of the solution is 100 milliliters, then 5 grams of the solute are present in that volume.

This concentration is essential in medical and clinical settings as it helps practitioners prepare solutions for various procedures effectively. By interpreting the 5% notation as 5 grams in 100 cc, it provides clear guidance for dosage and dilution requirements, ensuring that the concentrations used in treatments are accurate and safe for patient care.

In the context of the other options, they do not follow the standard definition of percent concentration: they either misrepresent the total volume associated with 5 grams of the solute or introduce incorrect units that do not align with the conventional understanding of a percentage solution.
