What is M/V (mass volume) concentration?

M/V (mass/volume) concentration refers to a quantitative measure where a specific amount of solute, expressed in mass (typically grams), is proportional to the volume of the solution, often given in milliliters. This type of concentration allows scientists to understand the amount of solute present in a specific volume of solution, making it particularly useful in preparing solutions in laboratories or in various applications within bioscience.

For instance, if a solution has a mass/volume concentration of 5 g/100 mL, it means that there are 5 grams of solute in every 100 milliliters of that solution. This measurement is critical in experimental setups where precise concentrations are necessary for proper reactions or analyses.

The other options do not accurately define M/V concentration. The first choice relates to pressure levels, which are unrelated to concentration. The third choice discusses temperature determination, which is also not connected to the concept of mass and volume concentration. Lastly, while percentages can be a way to express concentration, M/V specifically focuses on the relationship between absolute mass and volume, making it distinct from a mere percentage description.
