The chemical structure of the acid form of acetylsalicylic acid is shown below with its speciation plot. the dashed line shows the conjugate base form. acetylsalicylic acid (aspirin) the ph in the stomach is about 1, and in the intestine it is about 5. select the correct statement below: (a) the drug is absorbed from the intestine because it is in a neutral fat-soluble acidic form. (b) the drug is absorbed from the stomach because it is in a neutral fat-soluble acidic form. (c) the drug is absorbed from the intestine and the stomach because it is in a neutral fat-soluble form in both. (d) the drug is absorbed from the intestine because it is in a neutral fat-soluble basic form. (e) the drug is absorbed from the stomach because it is in a neutral fat-soluble basic form.

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

the formula for the conversion of temperature from degree celsius to kelvin is:

the sample of water at is converted to kelvin temperature by using the above formula as:

on comparing the two samples of water at or we can say that at and at respectively. the difference between the temperatures of two samples of water is:

hence, one can say that the sample of water at is greater than the sample of water at by .
