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 1.45x107 Pa, what is its running pressure in torr? Express the pressure numerically in torr. ► View Available Hint(s) 1.45x107 Pa = —| ΑΣΦ torr

![**Title: Understanding Pressure Conversions in High-Pressure Liquid Chromatography (HPLC)**
High-pressure liquid chromatography (HPLC) is a technique widely utilized in chemistry and biochemistry for the purification of chemical substances. The pressures employed in this method typically range from approximately 500 kilopascals (500,000 Pa) to about 60,000 kPa (60,000,000 Pa). Given the significance of precise pressure measurements in HPLC, it is often useful to express these values in torr.
**Example Problem:**
An HPLC procedure operates at a pressure of \(1.45 \times 10^7\) Pa. What is its running pressure when expressed in torr?
**Task: Convert the given pressure to torr.**
**Interactive Feature:**
The input field allows for the conversion of pressure from pascals to torr by providing the relevant numerical input.
**Conversion Box:**
\[
1.45 \times 10^7 \text{ Pa} = \_\_ \text{ torr}
\]
This educational conversion exercise aids learners in understanding the relationship between different pressure units and enhances their proficiency in applying this knowledge to practical scenarios in scientific research.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fe6e52c04-e2c3-4e2d-83a7-f5740c8e0fd5%2Ffa7b9bae-9616-4e20-8f04-649f052d7b2c%2Ftg3p1u5_processed.png&w=3840&q=75)
