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 3.65×108Pa , what is its running pressure in torr?
To convert the pressure from pascals (Pa) to torr, you can use the following conversion factor:
1 torr = 0.00750062 Pa
To find the pressure in torr, you can multiply the given pressure in pascals by the conversion factor:
Pressure in torr = Pressure in Pa × Conversion factor
Let's calculate the pressure in torr using the given pressure of 3.65×10^8 Pa:
Pressure in torr = 3.65×10^8 Pa × 0.00750062 torr/Pa
Pressure in torr ≈ 2,737,881.3 torr
Therefore, the running pressure of the HPLC procedure is approximately 2,737,881.3 torr.
