You're going to pre-weight an empty test tube, add ~4 drops of aniline, and then weigh the test tube again to determine exactly how much aniline you added. You'll need this number later to calculate a percent yield. After you added and weighed the aniline, add 6-7 drops of acetic anhydride.3. Calculate the theoretical yield aspirin if you start with 2.687 g of salicylic acid and an excess of acetic anhydride. Esguerra 6 4. If you were to start with 1.00 g of salicylic acid, what volume of acetic anhydride would be needed to completely react with it? The density of acetic anhydride is 1.082 g/mL. 5.When synthesizing aspirin, a student began with 3.20 mL of acetic anhydride (density = 1.08 g/mL) and 1.45 g of salicylic acid. The reaction was allowed to run its course and 1.23 grams of aspirin was collected by the student. Determine the limiting reactant, theoretical yield of aspirin and percent yield for the reaction.Calculate percent yield of aspirin (acetylsalicylic acid) when you start with 2 mL (.302 Moles used in experiment) of methyl salicylate and an excess of sodium hydroxide. Assume complete conversion. We ended experiment with a weight product of .954 g & melting point of 158.3 degrees Celsius. Please show work, thanks!Preparation of aspirin. A bath was prepared by using 400mL beaker was filled with half with water and it was heated until it boiling. 2.00g of salicylic acid was weighed and placed in 125mL dry conical flask. This quantity was used to calculate the theoretical yield of aspirin.The maximum or theoretical yield is based on the limiting reactant and cannot exceed 100%. In many cases, when a reaction is worked up, inefficiencies in removing unreacted starting materials ...Question: 3. Calculate the theoretical yield of aspirin if you started with 1.35 g of salicylic acid. What are some reasons that the actual yield of a reaction might be lower than the theoretical yield? 4. What are some reasons that the actual yield of a reaction might be higher than the theoretical yield? 5.Transcribed image text: Calculate the theoretical yield of aspirin if you started with 1.35 g of salicylic acid. 4. W hat are some reasons that the actual yield of a reaction might be lower than the theoretical yield? 5. What are some reasons that the actual yield of a reaction might be higher than the theoretical yield? 2C7H6O3 + C4H6O3 -> 2C9H8O4 + H2O. (a) If 15.0 g 2-hydroxybenzoic acid is reacted with 15.0 g. ethanoic anhydride, determine the limiting reagent in. this reaction. (b) Calculate the maximum mass of aspirin that could be. obtained in this reaction. (c) lf the mass obtained in this experiment was 13.7 g, calculate the percentage yield of aspirin.Show calculations for theoretical yield and percent yield to earn the full points indicated on the table. Theoretical yield: (2 points) (2.105 g sac. acid) x 1 mol. sac acid. x 1 mol aspirin x 180 g aspirin 138 g sac. acid. 1 mol sac. acid. 1 mol aspirin Percent yield:(2 points) given experiment, 1.50 g of copper was heated with excess sulfur to yield 1.46 g of copper(I) sulfide. Calculate the theoretical yield. What is the percent yield? 9. Two successive reactions: A! B and B ! C, have yields of 73% and 68%, respectively. What is the overall percent yield for the conversion of A ! C ? 10.The basis of this idea is first a balanced equation. Once the equation is balanced, calculate the theoretical yield. How to calculate theoretical yield. To calculate theoretical yield and ensure that the correct amount of each reactant is present to use all materials effectively, you can use the following formula as a basis. 1.The theoretical yield is what you calculate when you do a calculation on paper or before you do a reaction in a lab. The actual yield will always be less than the theoretical yield because no chemical reaction ever reaches 100 percent completion. In a lab setting, there's always some amount of error, whether it's big or small.Complete the following table for the naoh standardization B) Theoretical Yield . Formula: (Product yield from limiting reactant) x (Molar mass of product) 0.0145 moles of Acetylsalicylic Acid x 180. 157 g 1 mol Acetylsalicylic Acid = 2.609 g of Acetylsalicylic Acid C) Percent Yield . Percent Yield = Actual Yield Theoretical Yield x 100 1. 205 g 2. 609 g. x 100 = 46.2% yieldastro rockycredit union credit score requirementshow to wear a cowgirl hatvinted ukpeteol near mebath rugs target L2_1
