A researcher is often required to prepare solutions in the lab. Typically, a lab provides a concentrated solution. This solution must be diluted to the proper concentration. Hydrochloric acid is a common stock solution that is typically purchased at 37.0% HCl concentration (density = 1.20 g/ml). You must make 100 ml of 0.25 M HCl to do a DNA extraction experiment. How much of the 37.0% HCl concentration stock do you need to prepare this solution?
Calculate the volume of oxygen you would need at 1.00 atm and 298 K to completely oxidize 53g of glucose.
At a certain temperature, the solubility of cadmium fluoride, CdF2, is 0.162 mol/L. Calculate its solubility product constant for this temperature.
