Which is a false statement about the possible benefits of nanocars?

a. they could work together to build really complex things.

b. they could increase the efficiency of building computer chips.

c. they could increase the ability to build things from the top down.

d. they could work as medical submarines searching the body for disease.

step-by-step explanation:

whole numbers, zero or greater

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

c. 4.54 x 10–12 j happens to be correct
