Question

match each concentration with the correct expression.

• concentration
• concentration of a dilution
• mass/volume percent
• mass percent
• volume percent

amount of solute divided by the amount of solution
volume of the solute divided by volume of solution
the concentration of the stock solution multiplied by the volume of the stock solution is equal to the concentration of diluted solution multiplied by the volume of the diluted solution
mass of the solute divided by the volume of solution
mass of the solute divided by mass of the solution

Explanation:

• Concentration: It is a general term for the amount of solute relative to the amount of solution. So, "Amount of solute divided by the amount of solution" matches "Concentration".
• Volume percent: It is defined as the volume of the solute divided by the volume of the solution. So, "Volume of the solute divided by volume of solution" matches "Volume percent".
• Concentration of a dilution: The formula for dilution is \(C_1V_1 = C_2V_2\) (where \(C_1\) is the concentration of the stock solution, \(V_1\) is the volume of the stock solution, \(C_2\) is the concentration of the diluted solution, and \(V_2\) is the volume of the diluted solution). So, "The concentration of the stock solution multiplied by the volume of the stock solution is equal to the concentration of diluted solution multiplied by the volume of the diluted solution" matches "Concentration of a dilution".
• Mass/volume percent: It is calculated as the mass of the solute divided by the volume of the solution. So, "Mass of the solute divided by the volume of solution" matches "Mass/volume percent".
• Mass percent: It is the mass of the solute divided by the mass of the solution. So, "Mass of the solute divided by mass of the solution" matches "Mass percent".

Answer:

• "Amount of solute divided by the amount of solution" → "Concentration"
• "Volume of the solute divided by volume of solution" → "Volume percent"
• "The concentration of the stock solution multiplied by the volume of the stock solution is equal to the concentration of diluted solution multiplied by the volume of the diluted solution" → "Concentration of a dilution"
• "Mass of the solute divided by the volume of solution" → "Mass/volume percent"
• "Mass of the solute divided by mass of the solution" → "Mass percent"
