How can i estimate the % of methanol and water from a simple/fractional distillation?
madeulo0k asked:
Started out with 60 ml of the mixture. I represented graphically against the volume graph of temperature. Now I have to evaluate just how much of each I have a solution. thanks!

The boiling point of pure methanol is 64.7 degrees C at 760 torr.
The refractive index is 1.3292
The Bp of water is 100 degrees C at 760 torr and the refractive index is 1.3330.
You could try to plot the bp of water and methanol and hope that there is a linear relationship between bpt of mixtures and % volume.
Plot % volume on the x axis and the bpt of metahnol and water and the mixture on the y axis.
There is a linear relationship between refractive index and % volume using refractive index.
