The pressure in car tires is often measured in pounds per square inch (lb/in.2), with the recommended pressure being in the range of 25 to 45lb/in2. Suppose a tire has a pressure of 39.0lb/in22. Convert 39.0lb/in.2 to its equivalent in atmospheres. Express the pressure numerically in atmospheres. 39.0lb/ n 3 Incorrect; Try Again; 3 attempts remaining 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 (500,000Pa) to about 60,000kPa(60,000,000Pa). It is often convenient to know the pressure in torr. If an HPLC procedure is running at a pressure of 2.49108Pa, what is its running pressure in torr? Express the pressure numerically in torr
