Propane undergoes combustion with oxygen gas to produce carbon dioxide and liquid water according to the following equation. Balance this equation.
C3H8(g) + O2(g) → CO2(g) + H2O (l)

a. What volume of propane (C3H8) is required to produce .762 L of carbon dioxide gas at STP?

b. What volume of oxygen gas would also be required?

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
