Question

High-pressure liquid chromatography (HPLC) is a methodused in chemistry and biochemistry to purify chemicalsubstances. 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 of5.17x108 Pa what is its running pressure in torr?Express the pressure numerically in torr.

Answer 1

0.039x10^3 torr

Step-by-step explanation

1 Pascal (Pa) = 0.0075 torr

5.17x10^8 Pa = 0.039x10^3 torr
