Three liquids were poured into a beaker and formed three layers, as shown below. Which of the following conclusions can be made given the information seen in the picture? 200 ml 2 3 A The mass of Liquid 2 is greater than the mass of Liquid 3 B The volume of Liquid 1 is less than the volume of Liquid 3 C The density of Liquid 3 is greater than the density of Liquid 2 D The buoyancy of Liquid 2 is greater than the buoyancy of Liquid 1

c. is the answer

the formula mass of a molecule or a compound is the sum of the atomic weights of the atoms in its empirical formula

(that's what i know about formula mass)

the correct answer to this question is 2

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
