Step 1: Identify the correct definition of concentration
Concentration is a measure of the amount of solute present in a given amount of solvent or solution. It is used to describe how much of the substance of interest (solute) is present in a given quantity of a solution.
Step 2: Examine the given options
Option A: Ratio that describes the amount of solute divided by the amount of solvent or solution - This is the correct definition of concentration, as it describes the amount of solute relative to the amount of solvent or solution. Option B: Ratio that describes the amount of solvent or solution divided by the amount of solute - This definition is incorrect, as it describes the concentration in terms of the amount of solvent or solution relative to the amount of solute. Option C: Ratio that describes the mass of solute divided by the mass of solvent - This definition is a specific type of concentration called mass concentration, but it does not cover all types of concentration. Option D: Ratio that describes the amount of solvent in a solution - This definition is not a general definition of concentration, as it only describes the amount of solvent in a solution and not the amount of solute.
Final Answer
The correct definition of concentration is option A: Ratio that describes the amount of solute divided by the amount of solvent or solution.
