How to Use the Ochem Reaction Calculator

Using the Ochem Reaction Calculator is straightforward, even for beginners. Follow these simple steps:

Enter Substrate Amount: Input the amount of your starting material (substrate) in moles. This represents the primary reactant in your chemical reaction.
Enter Reagent Equivalents: Specify the number of equivalents of the reagent used relative to the substrate. This helps determine the actual amount of reagent needed for the reaction.
Enter Reaction Yield: Provide the expected yield of your reaction in percentage. The yield indicates how much product you can realistically obtain from the reaction.
Calculate Results: Click the “Calculate” button to instantly see the product amount in moles and the reagent required in moles.
Reset if Needed: Use the “Reset” button to clear all inputs and start fresh for a new calculation.

The calculator will instantly display your results in a clear and organized format, making it easy to record or use in your lab work.

Example: Using the Calculator

Let’s look at an example to understand how this tool can be applied:

Suppose you are conducting a reaction with 0.5 moles of substrate.
You plan to use 1.2 equivalents of the reagent.
The expected yield of the reaction is 85%.

Using the Ochem Reaction Calculator:

Product Amount (mol) = Substrate × (Yield ÷ 100) = 0.5 × 0.85 = 0.425 mol
Reagent Required (mol) = Substrate × Equivalents = 0.5 × 1.2 = 0.6 mol

Within seconds, the calculator provides the exact numbers you need to proceed with your experiment confidently.
