Which of the following is not a step in the scientific method? a. research b. existing sources report results c. receive corroboration from the field d. formulate a hypothesis

c. receive corroboration from the field

Explanation:

Following options are a step in scientific methods

a. Research

b. existing source report results

d. Formulate a hypothesis

Therefore only option does not come under scientific method is

c. receive corroboration from the field

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
