To monitor the rate of a chemical reaction colorimetrically, a student needs to prepare a standard calibration solution of copper(II) sulfate with a concentration of 0.12 mol dm-3. They have 80 cm3 of a stock solution of copper(II) sulfate with a concentration of 1.50 mol dm-3.
What is the maximum volume of the 0.12 mol dm-3 solution that can be prepared?
