you mix together 2.00L 0.80 M FeCL2 and 0.50L 0.60 M FeCL3. This starting solution must be diluted to a 4.00 0.60 M Cl- solution. How much of the starting solution should you mix with how much water to get this?

High-pressure liquid chromatography (hplc) is a method used in chemistry and biochemistry to purify chemical substances. the pressures used in this procedure range from around 500 kilopascals (500,000 pa) to about 60,000 kpa (60,000,000 pa). it is often convenient to know the pressure in torr. if an hplc procedure is running at a pressure of 1.03×108 pa , what is its running pressure in torr?
