Question

What is the ratio of pure drug to solution? Simplify, if necessary.

8%

There is/are _____ gram(s) of pure drug to _____ milliliters of solution.

Answer 1

The ratio of pure drug to solution for an 8% concentration is 8 grams of pure drug per 100 milliliters of solution, equivalent to 0.08 grams per milliliter.

Step-by-step explanation:

The ratio of pure drug to solution, when it is stated that the solution has an 8% concentration, means there are 8 grams of pure drug per every 100 milliliters of solution. This is because the mass-volume percent ratio is calculated by taking the mass of the solute (in this case, the pure drug) and dividing it by the volume of the solution, then multiplying by 100 to express it as a percentage. Here, we're told the solution is 8% drug, so for every 100 milliliters, there would be 8 grams of the pure drug.

To find the specific amount of drug per milliliter, we can set up the proportion based on the percentage given:

8 g / 100 mL = x g / 1 mL

Solving for x gives us:

x = (8 g / 100 mL) * 1 mL = 0.08 g/mL

So there are 0.08 grams of pure drug per 1 milliliter of solution. If a different volume is given, we can use this per-milliliter amount to scale up to the desired volume.
