1. What is Theoretical Yield?

The theoretical yield is the maximum amount of product that can be produced from a given amount of limiting reagent, based on the stoichiometry of the chemical reaction.

2. How Does the Calculator Work?

The calculator uses the theoretical yield formula:

\[ \text{Theoretical Yield} = \text{moles limiting} \times \text{stoich} \times \text{MW} \]

Where:

Explanation: The equation calculates the maximum possible mass of product based on complete conversion of the limiting reagent.

3. Importance of Theoretical Yield

Details: Theoretical yield is crucial for predicting reaction outcomes, calculating percent yields, and planning chemical syntheses.

4. Using the Calculator

Tips: Enter moles of limiting reagent, stoichiometric ratio, and molecular weight of product. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is the difference between theoretical and actual yield?
A: Theoretical yield is the calculated maximum, while actual yield is what you obtain experimentally, typically lower due to incomplete reactions or side products.

Q2: How do I find the limiting reagent?
A: Compare mole ratios of reactants to the stoichiometric ratio - the reactant with the smallest relative amount is limiting.

Q3: What units should I use?
A: Moles should be in mol, stoichiometric ratio is unitless, and molecular weight should be in g/mol.

Q4: Can this be used for any chemical reaction?
A: Yes, as long as you know the stoichiometry and have identified the limiting reagent.

Q5: How does this relate to percent yield?
A: Percent yield = (actual yield / theoretical yield) × 100%.
