) Calculate how much 95% ethyl alcohol will be required to dissolve 0.75 g of Sulfanilamide at 78℃ use the graph in technique 11, figure 11.2, to make this calculation. the reason for making this calculation is 80 that you will know ahead of time the approximate amount of hot solvent you will be adding. 2) Using the volume of solvent calculated in step 1, calculate how much Sulfanilamide will remain dissolved in the mother liquor after the mixture is cooled to 0℃.
