Example Exercise 11.1 Gas Pressure Conversion
2011 Pearson Education, Chemistry: Concepts and Critical Thinking, 6th EditionCharles H. CorwinExample Exercise Pressure ConversionFor each Conversion , we apply a unit Conversion factor related to units of standard Pressure .(a)To express the Pressure in atmospheres, we derive a unit factor related to the equivalent relationship in. Hg = 1 atm.(b)To convert to millimeters of mercury, we derive a unit factor related to the equivalent relationship in. Hg = 760 mm Hg.(c)To calculate the Pressure in pounds per square inch, we derive a unit factor related to the equivalent relationship in. Hg = psi.(d)To find the Pressure in kilopascals, we derive a unit factor related to the equivalent relationship in.
Ideal Gas Behavior. Since the temperature of each gas is 25 ° C, we know that the kinetic energy is the same for NH. 3. and NO. 2. At the same temperature, we know that lighter molecules move faster than heavier molecules. The molecular mass of NH. 3. is 17 amu and NO. 2. is 46 amu. Since NH. 3. is lighter than NO. 2, the ammonia
