[Unit 2.6] | Balanced Equations, Atom Economies & Percentage Yield

Question 1

Define Atom Economy and its equation.

Answer 1

• A measure of the quantity of reactants in a reaction become a desired product.

Atom Economy = (Mass/Mr Of Desired Product / Total Reactant Mass/Mr) * 100
• Atom Economy: Percentage (%)
• Mass: Grams (g)

Question 2

Define percentage yield and its equation.

Answer 2

• A measure of the quantity of a product produced in experimentation compared to the theoretical maximum.

• Percentage Yield = (Mass/Moles Produced / Mass/Moles Expected) * 100
