Determination of the composition of a mixture You will be given a multi-component mixture and will be required to determine (and confirm) the %composition of the mixture, obtain a sample of each component and to verify its purity and identity. 1g - Benzoic acid and 1g - napthelene in 20 ml toluene Basically Im asking how to seperate and recrystallize the benzoic acid and napthelene and getting the toluene by itself to get the most product closest to the original amount as possible. Any help would be appreciated as Im quite lost and We need to figure out an experimental design.
