The Ideal Gas Law 1.  Derivation a. Boyle’s Law: _______________ b. Charles’ Law: ______________ c. Avogadro’s Law:  ______________ d. Mix them all together and it yields PV=nRT, where R is the universal gas  constant (0.0821 L atm K -1  mol -1 ) i. Note:  Pressure is in atm, V is in L, n is in mol, and T is in K 2. Usage a. Can be used to find any of the variables in the equation  b. VERY easily  manipulated. Practice : 1.  A 5 g sample of Nitrogen gas is stored at 760 Torr and 25  ° C.  What is the volume that  the gas occupies? 2. A 185 g sample of Chlorine gas is stored at a temperature of 37

Unformatted text preview: atmosphere. If the gas is transferred to a 1 L vessel, what is the pressure of the gas? 3. A 6.584 mol sample of gaseous hexanes are heated from 25 °C to 100 °C. Pressure is maintained at 50,000 pa, and the initial volume is 2.5 L. What is the final volume? 4. A 500 mL sample of 6M aqueous Dimethylformamine (B.P 155 °C) is heated until all of the DMF evaporates from solution. The pressure is maintained at atmospheric pressure. How much volume does the gas occupy once the phase change occurs?...

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
