Bringing It Together: Question 13.28 At a certain temperature a 35.27% (v/v) solution of ethyl alcohol, C2H5OH, in water has a density of 0.9183 g mL-1. The density of ethyl alcohol at this temperature is 0.7817 g mL-1, and that of water is 0.9927 g mL-1. Calculate the molar concentration of ethyl alcohol. ______________M Calculate the molal concentration of ethyl alcohol.___________________m Calculate the mole fraction of ethyl alcohol in the solution._______________ If the vapor pressure of ethyl alcohol at this temperature is 41.0 torr and the solution is ideal, what is the pressure of ethyl alcohol above this solution? _________________________torr If the vapor pressure of water at this temperature is 17.5 torr and the solution is ideal, what is the pressure of water above this solution? __________________________- torr
