Starting with 7.2 g of salicylic acid, how many grams of
acetylsalicylic acid (theoretical yield) can be made? Assume
salicylic acid is the limiting reagent and a one to one
stoichiometry. Use the molecular weights that you have already
calculated. Give two significant digits.
Calculate the theoretical yield of the ester formed by the acid
catalyze reaction of 10.0ml of isobutyl alcoholic and 12.0ml of
propionic acid.
Someone please help me with these calculations, I don't even
know the ester.
Determine the theoretical oxygen demand for the following
solutions:
(a) 200 mg/L of acetic acid, CH3COOH
(b) 40 mg/L of ethanol. C2H5OH
(c) 64 mg/L of sucrose,
C2H12O6.
All reactions are of the form: CH3COOH +
O2 >> CO2 + H2O
a) Calculate the theoretical yield of your product. The
theoretical yield should be quoted as a mass, not a number of
moles. Units must be shown on all numbers that need them.
Calculations that are done with an incorrect number of significant
figures will be counted as incorrect. Your work must be shown.
b) Calculate the percent yield for your product. This
calculation should be done with masses of your product and the
theoretical yield, not the number of moles....
