Question

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 5.05×10^8 Pa , what is its running pressure in torr?

Answer 1

3787500 Torr

Step-by-step explanation:

1 Pascal = 0.0075 Torr

So:

5.05x10^8 Pa --- x

1 Pa --- 0.0075 Torr

x = 5.05x10^8 × 0.0075

x = 3787500 Torr
