You need to prepare a solution of .25 M HCl for the experiment you are doing today. You only have the commercially available concentrated HCl (28 % w/w) on hand. The experiment requires using HCl at three points, each using a volume of 15 milliliters. Describe how you would prepare the required amount of HCl (in exact quantities of stock HCl and water) prior to doing the experiment. Assume the density of water and the HCL solution (which is mostly water) is exactly 1.0 g/ml.
