Question

1:500 solution has a dosage strength of

a. 1 g of medication per 500 mL solution.
b.5 g of medication per 100 ml solution.
c. 500 g of medication per 1 L solution.
d. 1 g of medication per 1,000 ml solution,

Answer 1

A 1:500 solution indicates that there is 1 gram of medication per 500 mL of solution, which corresponds with option (a).

Step-by-step explanation:

The question asks to identify the correct dosage strength for a 1:500 solution. Option (a) states that this would be 1 gram of medication per 500 milliliters of solution, which is the correct interpretation of the ratio 1:500. Therefore, for every 500 mL of the solution, there is 1 g of the medication dissolved in it.

To elaborate on concentration terms, mass percentage shows the mass of the solute in proportion to the total mass of the solution. Parts per million (ppm) and parts per billion (ppb) are measures of concentration for highly dilute solutions, equating to milligrams and micrograms of solute per kilogram of solution, respectively. Dilute aqueous solutions are occasionally estimated by these same mass units per liter of solution, assuming the density is 1.0 g/mL.
