Question
The graph given below plots the (approximate) partial molar volumes of ethanol (black
line) and water (red line) in units of ml/mole at 25°C in a mixture as a function of the mole
fraction of ethanol. Use the information in this graph (note the different y axes for water
and ethanol) and the densities at 25°C to calculate the resulting total volume of the
g
following two mixtures.(pethanol
= 0.789
ml
& PH20 = 0.998 )
ml
