Can someone please help me how to calculate the theoretical
yield from this chart?
I am so confused
This is the chart that I was given and Distillate V-2 is the
last part of the chart. This is the part of preparation and
reaction of alkene lab, and only using Distillate V-2 not V-1.

Given the amounts of reactants, please calculate the theoretical yield of the expected alkene reaction product, in mL. Do not factor the sulfuric acid into your calculations. Your final answer must appear in the box provided, or it will not be counted. 4-methylcyclohexanol ------H2SO4(aq) -----> 4-methylcyclohexene Molecular Weight (grams/mole) 114.2 g/mol 98.08 g/mol 96.2 g/mol density (grams/mL) 0.914 g/mL 0.799 g/mL volume (mL) 28.0 mL mass (grams) moles Theoretical yield in mL=

PRELAB EXERCISE EXPERIMENT 21 Synthesis of Aspirin (Acetylsalicylic Acid) What is the purpose of sulfuric acid or phosphoric acid used in the acetylation reaction? Use equations to explain this purpose. The procedure calls for cautious addition of water to the reaction mixture while it is still hot. What purpose does the addition of water serve and why should the addition be done while the reaction mixture is hot? Provide an equation for the reaction involved.Using the quantities of salicylic acid and acetic anhydride...
