Question

Part B Review Constants Periodic Table 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 as well as with the walls of the container. These collisions generate pressure. The pressure of a gas can be measured in different units. One convenient unit of measure is called the atmosphere (atm) because it is based on atmospheric pressure. At sea level, the average pressure is 1 atm. As you get higher in altitude, the pressure steadily drops until you leave the atmosphere, where the pressure is very close to O atm. The pressure in cartires is often measured in pounds per square Inch (b/in.') with the recommended pressure being in the range of 25 to 45 lb/in.. Suppose a fire has a pressure of 35.5 lb/in?. Convert 36.5 lb/in.to its equivalent in atmosphere Express the pressure numerically in atmospheres. View Available Hint(s) % AED + OB? 36.5 lb/in. - The table below shows the different commonly used units of measuring gas pressure.

Hg Submit Part pounds per square inch (psi) 1b/in.? 14 7 lb/in2 pascal Pa 101,325 Pa High-pressure liquid chromatography (HPLC) is a method used in chemistry and biochemistry to purity chemical substances. The pressures used in this procedure range from around 500 kilopascals (500,000 Pa) to about 60,000 kPa (10,000,000 Pa) It is often convenient to know the pressure in torr. If an HPLC procedure is running at a pressure of 1.81x10 Pa, what is its running pressure in ton? Express the pressure numerically in torr

Answer 1

Date : to (a) we have to convert Z h lth ets equivalent atmospheree we know from the conversion table dara latme pressure = 14.7 16 1162 Hence 36.5 161 162 can be converted into number of atmosphere pressure bry ! dividing 14.7 1blin2 Hence atmospheric pressure - 36061bline 14 7 16115 -2.483 atm. Pregune, Hence 36.5 lblin2 ie Ghis pounds per square inch (psi) is equal to 2.483 atm. Pressure (b) Here we have to convert 1.81 110 pa into torr. we know lat pressure = 101 oaspa 2 and latm = 460 toor Hence 1.81410 pa can be converted into number of atm by deviding lobaspa. Hence number of aton. pressure - 1.81 flore 101325 p 71-786 am Flence 1.786 atm rouressure wall equal to number of tooryt 1.4861 totust, =1354.57 toor 62 Hence 1.8140 pa y equal to 1357. 364oor.
