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 ) to about 60,000 (60,000,000 ). It is often convenient to know the pressure in torr. If an HPLC procedure is running at a pressure of 5.17×108 , what is its running pressure in torr? Express the pressure numerically in torr.
