Question

emView?assignmentProblemID-96489158 ?) 20112 (> Part C High-pressure liquid chromatography (HPLC) is a method used in chemistry and biochemistry to purity chemical substances. The pressures used in t to about 60,000 kPa (60,000,000 procedure is running at a pressure of 104-108 Pa, what is its running pressure in to? Express the pressure numerically in torr. his procedure range from around 500 kilopascals (500.000 Pa) Pa) It is often convenient to know the pressure in torr. If an HPLC View Available Hint(s) 1.04 10 Pa7.8 10 torr Submit X Incorrect: Try Again; 4 attempts remaining 499

Explanation / Answer

Ans. Given, Pressure, P = 1.04 x 108 Pa

            Using: 1 Pa = 0.00750062 torr = 7.50062 x 10-3 torr

Pressure, P = 1.04 x 108 Pa = 1.04 x 108 x (7.50062 x 10-3 torr) = 7.8 x 105 torr
