A solution contains naphthalene C10H8 dissolved in hexane C6H14 at a concentration of 10.33% napthalene by mass.
Calculate the vapor pressure at 25 degree C of hexane above the solution. The vapor pressure of pure hexane at 25 degree C is 151 torr
calculate delta U and delta H for the process on the basis of 1 mol of gas. Assume for the gas that PV/T is constant, Cv= (5/2)R, and Cp=(7/2)R.
