Final answer:

A 1.0 % (m/v) clindamycin antibiotic signifies that there is 1 gram of the medication in every 100 milliliters of the ointment. To calculate the amount of clindamycin in a capsule, one would multiply the volume of the capsule by the percentage (expressed as a decimal). In a 45 mL capsule, this amounts to 0.45 grams of clindamycin.

Step-by-step explanation:

The statement "A topical antibiotic is 1.0 % (m/v) clindamycin" implies that in every 100 milliliters of the topical antibiotic, there is 1 gram of the active ingredient clindamycin. To calculate the amount of clindamycin in a given volume of solution:

Multiply the volume of the solution by the percentage (expressed as a decimal).

For example, to find out how many grams of clindamycin are in a 45 mL capsule of the 1.0% (m/v) clindamycin, we perform the following calculation:

45 mL x 0.01 (1.0% as a decimal) = 0.45 grams of clindamycin

This calculation helps determine the dosage of an antibiotic that a patient is receiving with each application of the ointment.
