The Most Common Stomach Ulcer Symptoms. Stomach ulcers (often called peptic ulcers) are painful sores that develop in the lining of your digestive system. They usually form in the stomach but can also sometimes develop in the small intestine (especially a part called the duodenum) or the esophagus. Ulcers can cause a range of symptoms, some that are more mild and go away quickly, but others that linger and cause a good deal of pain.
Definition of Theoretical Yield. Maximum amount of a specified product that could be obtained from specified amounts of reactants, assuming complete consumption of limiting reactant according to only one reaction and complete recovery of product. (Compare with Actual Yield). Search the Dictionary.
The percentage yield (or fractional yield or relative yield), which serves to measure the effectiveness of a synthetic procedure, is calculated by dividing the amount of the desired product obtained by the theoretical yield (the unit of measure for both must be the same): The theoretical molar yield is 2.0 mol (the molar amount of the limiting compound, acetic acid). 2  The molar yield of the product is calculated from its weight (132 g Ã· 88 g/mol = 1.5 mol).
