Question

Asprin C9H8O4 is made by the reaction of salicylic acid C7H6O3 and acetic anhydride C4H6O3. The other product in the reaction is acetic acid HC2H3O2. How many of each reactant should be used to produce 75.0g of asprin. Assume that the reaction gives a 68.2% yield.

Answer 1

write and balance the chemical reaction.

change 75g aspirin to moles of aspirin. Now multiply that by 1/.682.

Now, use the mole ratio to determine each reactant from the balanced formula.
