How do you find the chemical formula?
Divide the molar mass of the compound by the empirical formula mass. The result should be a whole number or very close to a whole number. Multiply all the subscripts in the empirical formula by the whole number found in step 2. The result is the molecular formula.
What is the chemical reaction of aspirin?
Aspirin binds to and acetylates serine (an amino acid used by the body to make proteins) residues in the active site of cyclooxygenase enzymes, leading to reduced production of prostaglandin. This in turn mediates aspirin’s effect of reduced inflammation and pain in affected tissues.
What type of reaction is the synthesis of aspirin?
substitution reaction
The synthesis of aspirin is known in organic chemistry as an esterification reaction. This is a substitution reaction in which an alcohol (the –OH group in salicylic acid) reacts with acetic anhydride to form an ester, aspirin.

How is a chemical equation written?
In a chemical equation, the reactants are written on the left, and the products are written on the right. The coefficients next to the symbols of entities indicate the number of moles of a substance produced or used in the chemical reaction.
