An internal standard calibration curve was generated for the determination of ethyl acetate by gas chromatography, using butyl acetate as an internal standard. The equation of the best-fit line was y = 0.0588x (-0.0172). When an unknown was injected, peak areas of 82 and 9.0 × 101 were obtained for ethyl acetate and butyl acetate, respectively. Determine the concentration of ethyl acetate (%v/v) in the unknown.

The level of ethyl acetate (from which colchicines is precipitated from) is determined in colchicine by headspace gas chromatography. A 10 mL aqueous solution containing 0.1361g of the sample of colchicine was prepared. The USP allowed limit of ethyl acetate in colchicines is 8% by weight. An aqueous standard containing 0.1078 mg/10mL of ethyl acetate was also prepared. Both solutions also had n-propyl alcohol added in equal proportions representing the internal standard. Each chromatogram had two peaks, one from ethyl...

Use gibbs distribution to calculate the average entropy, energy and pressure of a single classical particle of mass m, with no internal degrees of freedom, free to move in volume V at temperature T. For that you will need to know the volume Vd of an d-dimensional hypersphere of the unit radius. (Vd=pi^(d/2)/gamma(d/2+1))
