This tool helps you easily calculate the products of organic chemistry reactions based on the reactants you input.
Organic Chemistry Reaction Calculator
Use this calculator to compute the actual yield of a reaction based on the amount of reactant, reactant molecular weight, product molecular weight, and the percentage yield.
How to Use
- Enter the amount of reactant in moles.
- Enter the molecular weight of the reactant in grams per mole (g/mol).
- Enter the percentage yield of the reaction.
- Enter the molecular weight of the product in grams per mole (g/mol).
- Click the “Calculate” button to obtain the actual yield.
How It Calculates Results
The calculator first computes the theoretical yield based on the stoichiometric ratio of reactant and product weights. This is done by the formula:
Theoretical Yield = (Reactant Amount * Product Molecular Weight) / Reactant Molecular Weight
Then it calculates the actual yield by applying the yield percentage:
Actual Yield = (Theoretical Yield * Yield Percentage) / 100
The result will be displayed in grams.
Limitations
- Make sure to enter all fields correctly. Incorrect values will result in inappropriate calculations.
- This calculator assumes a one-to-one molar ratio between reactant and product. It won’t account for more complex stoichiometries.
- Yields higher than 100% are not physically meaningful and should be scrutinized or considered for error in inputs or experimental methods.
Use Cases for This Calculator
