Given this balanced equation: 1 K2CrO4 + 1 Pb(NO3)2 -> 1 PbCrO4 + 2 KNO3

If you want to make 28.49 moles of KNO3 , how many mole of Pb(NO3)2 do you need?

organisms are more likely to be more preserved in mud than sand because mud is moist and wet, while sand is very dry.

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
