Final answer:
To calculate the mass/volume percent concentration, divide the mass of the solute by the volume of the solution and multiply by 100. This represents the mass of solute in every 100 milliliters of the solution, which is crucial for exact dosing in clinical and chemical applications.
Step-by-step explanation:
To calculate the concentration of a solution in mass/volume percent (m/v%), you need to know the mass of the solute (in grams) and the volume of the solution (in milliliters). The m/v% concentration is defined as the mass of solute divided by the volume of solution times 100%. For example, if you have a solution with 5 grams of solute in 250 milliliters of solution, the m/v% concentration would be calculated as follows:
- (5 grams solute / 250 mL solution) × 100% = 2% m/v%
This means there are 2 grams of solute for every 100 milliliters of solution. Mass/volume percent is a significant measurement, especially in clinical settings, because it allows for the direct comparison of the amount of substance in a given volume, enabling precise dosages and reagent levels in treatments and reactions.
