Hydrocarbons are compounds that are composed of carbon and hydrogen. which statement does the law of definite proportions support?
a. each sample of a single hydrocarbon has the same mass ratio of carbon to hydrogen
b. the mass ratio of carbon to hydrogen is the same for each hydrocarbon
c. no to hydrocarbons have the same mass ratio of carbon to hydrogen
each hydrocarbon can have several mass ratio of carbon to hydrogen depending on its source

i think the answer is terrae but not 100 percent sure. ▓▬▬ §

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
