Answer: 8.9

Answer: 1857 N/m

Three extractions with 60mL portions of chloroform removed 98% of a solute from 200mL of an aqueous solution. What is the partition coefficient of the solute? The vibrational transition from v=0 to v=1 for carbon monoxide occurs at a wavenumber of 2143.3cm1. Calculate the value of the force constant of the CO bond in Nm1. Assume that the molecule behaves like a simple harmonic oscillator. Express your answer in four significant figures. mc=12.01amu,m0=16.00amu,1amu=1.6611027kg =3.142,h=6.6261034Js,c=2.998108ms1
