A sample of nitrogen gas is in a 65.0-L automobile air bag and has a pressure of 745mm Hg. What is the pressure of this sample of gas at the same temperature if it is placed into a 25.0-L bag?
(a) 1940 mm Hg
(b) 5.15 x 10-4 mm Hg
(c) 745 mm Hg
(d) 287 mm Hg

it’s previous models   because when i picked that son of a gun’s answer it was wrong look for previous models because they might make it a different letter  

answer : (a) volume of the gas = 8.67 ×   l

                (b) second virial coefficient b = -1.21226 l/mole

solution :   given,     t = 300k

                                p = 20atm

                                z = 0.86

                                n = 8.2 mmoles = 8.2 × moles

                                r =   0.082 l atm/k/mol

        find,     (a) volume of gas   and (b) second virial coefficient b at 300k.

formula used :            

                          and            

(a)            

                    = \times 0.082\times 300}{20}[/tex]

                    = 8.67 ×   l

(b)      

                    = (0.00867-1) × 8.659

                    = - 8.5839 l/mole
