Ok, so I am taking orgo 1 right now and I am completely stumped. Any one have any ideas on how to answer this lab question?
How would I solve this problem? If it seems trivial to you, I apologize. I am just really confused
A crude sample has a mass of 3.4 grams; 3.1 grams of this sample are compound P [the desired material] and 0.3 grams of impurity I. A student in an organic chemistry lab was assigned the project of purifying compound P by the technique of recrystallization.
Compound P and impurity I have the following solubility properties in the recrystallization solvent. These solubility properties of compound P and impurity I in the recrystallization solvent are for these two components individually and in the presence of one another.
Solubility in Recrystallization Solvent
Compound P 0.4g/mL 75oC
Impurity I 0.3g/mL 75oC
Compound P 0.1g/mL 10oC
Impurity I 0.1g/mL 10oC
Based upon the above information, what is the percent recovery of compound P? Calculate the percent recovery of compound P on the amount of compound P in the initial crude sample.
