What is the formula for predicting the grams of Aspirin produced from reacting Salicylic Acid and Acetic Anhydride?
It's a four step process.
1. Write and balance the equation.
2. Convert grams SA to mols unless AA is given in which case convert that to mol. mols = grams/molar mass.
3. Using the coefficients in the balanced equation convert mols from step 2 to mols of aspirin.
4. Now convert mols aspirin to grams. g = mols x molar mass.
Thank you, I was stumped!
To predict the grams of Aspirin produced from the reaction between Salicylic Acid and Acetic Anhydride, you'll need to use the concept of stoichiometry, which is the quantitative relationship between reactants and products in a chemical reaction.
The balanced chemical equation for the reaction between Salicylic Acid (C7H6O3) and Acetic Anhydride (C4H6O3) to produce Aspirin (C9H8O4) is:
C7H6O3 + C4H6O3 → C9H8O4 + CH3COOH
To calculate the grams of Aspirin produced, you need to know the mass of Salicylic Acid used and utilize the stoichiometric ratio between Salicylic Acid and Aspirin.
Here are the steps to calculate the grams of Aspirin produced:
1. Start with the given mass of Salicylic Acid (C7H6O3).
2. Convert the mass of Salicylic Acid to moles using the molar mass of Salicylic Acid (molar mass = sum of atomic masses).
3. Use the balanced equation to determine the mole ratio between Salicylic Acid and Aspirin. In this case, the ratio is 1:1 as indicated by the coefficients in the balanced equation.
4. Use the mole ratio to calculate the number of moles of Aspirin produced.
5. Convert the moles of Aspirin produced to grams using the molar mass of Aspirin (molar mass = sum of atomic masses).
6. The resulting value is the predicted grams of Aspirin produced.
It's important to note that the actual yield of the reaction may be less than the predicted value due to various factors such as incomplete reactions or side reactions.
