Knowing the concentration of a solution allows us to find all of the following except
A. the mass of a solute.
B. the mass of the solvent.
C. the volume of the solvent.
D. the concentration of a solution when conditions change.
To answer this question, let's first understand what concentration of a solution means. Concentration refers to the amount of solute dissolved in a given amount of solvent or solution. It is usually expressed as a ratio or a percentage.
Now, let's examine each of the answer choices:
A. Determining the mass of a solute: By knowing the concentration of a solution, you can calculate the mass of the solute involved. This is because concentration is a measure of how much solute is present in a solution.
B. Determining the mass of the solvent: The concentration of a solution does not directly provide information about the mass of the solvent. The concentration focuses on the amount of solute present, not the solvent.
C. Determining the volume of the solvent: Similarly to the previous answer, the concentration of a solution does not provide direct information about the volume of the solvent. It is solely concerned with the amount of solute.
D. Determining the concentration of a solution when conditions change: This statement is incorrect. Knowing the concentration of a solution is crucial for determining how the concentration changes when conditions, such as temperature or pressure, are altered. Concentration is a dynamic property that can be affected by external factors.
From the analysis above, we can conclude that the correct answer is B. the mass of the solvent. The concentration of a solution does not directly give information about the mass of the solvent; it solely focuses on the solute.
I don't know the answer because it varies with what kind of concentration you have. g/L, M, m,% w/v, %w/w, % v/v.
Frankly I think this is a poor question.
