Next, it is time to write your own short story. Regardless of the factors involved in your real-life case, you will need to alter this case to not only make it your own creative endeavor, but also to include and meet the following requirements: Minimum of two pages
Includes and highlights physical evidence in the form of blood, fingerprints, and hair or other DNA
Physical evidence needs to be a main focus in your story – for example, perhaps the physical evidence is what helps to solve the case and catch the culprit or perhaps the physical evidence is mishandled and deems the case unsolvable.

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
