1. Dr. Bayul studies rock formations all over the world. She is working on a study of two rock formations. The information from the study is as follows:
• Rock A formed from liquid rock.
• Rock B formed from small pieces of rock in a different place.
• Rocks A and B formed at about the same time.
Are Rocks A and B the same or different types of rock?
The rocks are
a the same type because they both formed from rock material.
b the same type because they formed at the same time.
c different types because they formed in different ways.
d different types because they formed in different places.

hi my dude or dudette

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
