Question

cookin oil comprise of a mixtureof compounds which have a boiling point range of 23 degree to 27degree. what evidence is then to support the statement that cooking oil is a mixture?Name another experimental technique that could be used to confirm your answer?

Answer 1

Explanation:

A scientist studied the dynamic adsorption of gas M on silica gel (BP). The following amounts of adsoprtion (in moles per kilogram) was collected at 27 °C. Ρ/ΚΡα n/mol kg" 31.00 38.22 53.03 76.38 101.97 130.47 165.06 182.41 205.75 219.91 1.00 1.17 1.54 2.04 2.49 2.90 3.22 3.30 3.35 3.36 (1) (ii) Find the value of n that corresponds to complete coverage. Find the rate constant of desorption if the rate constant of adsorption is 0.00145 s. Find the surface area of silica gel (in m²) if a molecule of gas M occupied 0.03 pm (iii)
