Convert 1000.0 mm/s to km/hr. (1 km= 1000 m, 1 m = 1000 mm, 1 hr = 3600 S )

Explanation:

1 km =1000 m

1km=1000000 mm then

1mm=1/1000000=1*10^-6

1 hour =3600 sec

1 sec=1/3600=2.8*10^-4 hr

now

1000.0 km/hr=1000.0*1*10^-6/2.8*10^-4=3.571 mm/s

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
