You have a large amount of 8.00 M stock solution. You need 1.40 L of 2.50 M solution for an experiment. How would you prepare the desired solution without wasting any stock solution?
These are the answer choices:
(1). Start with 1.40 L of water. Add stock solution until you reach a total volume of 2.04 L .
(2). Start with 1.40 L of the stock solution. Add water until you reach a total volume of 4.48 L .
(3). Start with 0.438 L of the stock solution. Add water until you reach a total volume of 1.40 L .
(4). Mix 0.700 L each of stock solution and water.
