Unformatted text preview: Xue Dong chem.12a lab 01 Lab partener: Patrick keenan, Shayon Shahbazi SYNTHESIS OF ASPIRIN Date analysis Initial weight of salicylic acid is 0.025g The molecule mass of aspirin is 180.16g/mol Moles of a molecule=mass of substance / molar mass Mass of a substance =Moles of a substance * Molar mass 180.16g/mol*0.016mol=0.288g aspirin The percentage yield for this synthesis of aspirin can be calculated as follow Maximum yield=0.288g Actual yield=0.1158g Percentage yield= Actual yield./Maximum yield=40.21% Final produce Maximum yield =0.288g Actual yield=0.0377g Percentage yield=actual yield/maximum yield=86.9%% Crude product Average of actual melting range=136 Expected melting point=139c Percentage error=-2.15% Final product Average of actual melting range=136 Expected melting pointu 147.3c Percentage error=u 7.48% Data analysis The first line shows how much acetylsalicylic acid was used. Since there is a 1;1 ratio between the salicylic acid and aspirin, the theoretical yield of aspirin could be calculated...
