At a certain temperature a 44.13%(v/v) solution of ethyl alcohol, C2H5OH, in water has a density of 0.8954gmL1. The density of ethyl alcohol at this temperature is 0.7730gmL1, and that of water is 0.9921gmL1. Calculate the molar concentration of ethyl alcohol. M eTextbook and Media 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
