The pressure inside a pressure cooker is 2.0 atm. How many minutes will it take to cook 1.0 pound of potatoes in a pressure cooker if it takes 45 minutes to cook them in boiling water at standard pressure? Given: volume of the pressure cooker is 4.0L, there are 0.25 gaseous moles, and E_a = 1.77 x 10^55 J/mol.

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?
