1. What is a Theoretical Yield Calculator?

Definition: This calculator determines the theoretical yield of a chemical reaction based on the mass of a reactant, its molecular weight, and stoichiometry, step by step.

Purpose: It is used in chemistry to calculate the maximum amount of product that could be formed in a reaction, assuming 100% efficiency, aiding in reaction planning and analysis.

2. How Does the Calculator Work?

The calculator follows these steps, using the theoretical yield formula:

\[ n_{\text{lim}} = \frac{m_{\text{lim}}}{m_{\text{mol,lim}} \cdot c_{\text{lim}}} \] \[ m_{\text{product}} = m_{\text{mol,product}} \cdot n_{\text{lim}} \cdot c \]

Where:

\( m_{\text{product}} \): Mass of product
\( m_{\text{mol,product}} \): Molecular weight of the desired product
\( n_{\text{lim}} \): Moles of the limiting reagent
\( m_{\text{lim}} \): Mass of limiting reagent
\( m_{\text{mol,lim}} \): Molecular weight of the limiting reagent
\( c_{\text{lim}} \): Stoichiometry of the limiting reagent
\( c \): Stoichiometry of the desired product

Explanation: Enter the mass of the limiting reagent (e.g., 10 g), molecular weight of the limiting reagent (e.g., 18 g/mol for water), stoichiometry of the limiting reagent (e.g., 1), stoichiometry of the desired product (e.g., 1), and molecular weight of the product (e.g., 36 g/mol). The calculator performs the steps above and outputs the moles of the limiting reagent and theoretical yield in various units.

3. Importance of Theoretical Yield

Details: Theoretical yield represents the maximum product possible, providing a benchmark for reaction efficiency, helping identify losses, and guiding experimental design in chemical synthesis.

4. Using the Calculator

Tips: Input the mass, molecular weights, and stoichiometry values with their units. Ensure all values are positive, and molecular weights and stoichiometries are non-zero to avoid division errors. Stoichiometry values should reflect the balanced chemical equation for accurate results, with the limiting reagent and desired product specified correctly.
