When solving Gas law problems, make sue the units match up
Example problems
Example #1: (combined gas law) V1= 200L, P1= 300mm Hg, T1= 293.15K, P2= 1 atm, T2= 273.15K. What is V2? (P1 x V1)/T1 = (P2 x V2)/ T2 The answer is 73.561 L
Example #2: (ideal gas law)
P=725mm Hg, n=.54 moles, R= 62.4 moles (gas constant look at reference table), T= 253.15K. What is V? PV=nRT-----------> v= 8530.14/725----> V= 11.7L
