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

Concentration is the amout of solute present in a given amount ( mass or volume ) of solution or of solvent.

Solute = 4mL

Solvent = 60 mL

Concentration = Amount of solute / Amount of solvent or solution = 4 mL / 60mL = 0.66 mL
