Define concentration. If 4mL of acetone is present in 60 mL of its aqueous solution, calculate the concentration of this solution.
You are correct.
Concentration is defined as the amount of solute dissolved per amount of solution.
Concentration = amount of solute/amount of solution
Given data
Amount of acetone = 4mL
Amount of solution = 60 mL, therefore
Concentration = amount of solute/amount of solution
= 4mL/60mL
= 0.0667
