Which of these is a significant ethical dilemma that a drug designer may face?
A. A new drug effectively fights allergies but causes drowsiness.
B. A new drug treats hypothyroidism but destroys the thyroid; this
means that patients will be on the drug indeterminately,
C. A new drug effectively treats skin cancer but may cause minor
skin rashes during treatment.
O D. A new drug effectively lowers blood pressure but may cause
headaches.

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.

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
