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 3.46x108 Pa, what is its running pressure in torr?
Express the pressure numerically in torr.
