HELP ME PLS THIS IS SCIENCE The skeletal system of an animal provides support internally, giving the body a rigid component so that it keeps its shape. In a plant cell, which pair of organelles provide this internal and external support as the skeletal system would in an animal body? Select ALL that apply. A)nucleus
B)cell wall
C)cytoplasm
D)chloroplast
E)large central vacuole

a

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
