in a paragraph of 150 words or more describe how you could use reasearch and the scientific method to test a claim that organic food are better than natural foods. use complete sentences, state your hypothesis and explain specifically how you would conduct the reasearch and gather the data that you will use. You do not have to conduct the experiment only explain what you would do and how you would analyze the results.​

im not exactly sure but i think its b!

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)

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
