ligh-pressure liquid chromatography (HPLC) is a method used in chemistry and biochemistry to purify chemical ubstances. The pressures used in this procedure range from around 500 kilopascals (500,000 Pa) to about 60,000 kPa 50,000,000 Pa). It is often convenient to know the pressure in torr. If an HPLC procedure is running at a pressure of .26×10® Pa , what is its running pressure in torr? Express the pressure numerically in tor.

Part C
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
1.26x108 Pa , what is its running pressure in torr?
Express the pressure numerically in torr.

Part B
The pressure in car tires is often measured in pounds per square inch (Ib/in.), with the recommended pressure being in
the range of 25 to 45 lb/in.2. Suppose a tire has a pressure of 42.5 lb/in.? . Convert 42.5 lb/in.? to its equivalent in
atmospheres.
