Question

Gases are different from solids and liquids. In a sample of gas, the molecules are far apart. The gas molecules also move around and collide with each other in well as with the walls of the container. These collisions generate. The procure of a gas can be measured n different units. Ore convenient unit of measure is called the atmosphere (at in) because it is based on atmosphere pressure. At sea level, the average pressure is 1 atm. As you get higher in attitude the pressure Steady drops until you leave the atmosphere, where the pressure is very close to 0 at in. The table below shows the different commonly used units of measuring gas pressure. Use this table in the pressure unit conversions. The pressure in car tires is often measured in pounds pot square inch (lb/in^2), with the recommended pressure being in the range of 25 to 45 lb/in^2. Suppose a tire has a pressure of 41.0 lb/in^2. Convert 41.0 lb/in^2 to its equivalent in atmospheres. Express the pressure numerically in atmospheres. 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 kill (500.000 Pa) to about 60.000 k Pa (60.000 000 Pa). It is often convenient to know the pressure in tore. It an HPLC procedure is running at a pressure of 4.68 times 10^8 Pa what is its running pressure in tore? Gases are different from solids and liquids. In a sample of gas, the molecules are far apart.

Explanation / Answer

Part B:

1 atm = 14.7lb/in2

1 lb/in2 = 1/14.7atm

41.0lb/in2 = 41.0/14.7atm= 2.789atm

Part B:

1 pascal = 0.0075torr

4.68*108Pa = 4.68*108*0.0075 = 3.51*106torr
