General Chemistry Calculators
Work with moles, concentrations, reaction yields and titration stoichiometry.
Turn a balanced equation and a clearly labeled set of quantities into a calculation. These tools support introductory chemistry for science, engineering and health-science students.
Convert mass to moles first, compare reactants using their balanced coefficients, then calculate yield. For solutions, distinguish final solution volume from solvent added. For titration, apply the reaction ratio at equivalence.
These are educational calculations. The dilution tool does not model volume contraction or chemical reactions; the titration tool calculates stoichiometric concentration, not a full titration curve or experimental endpoint.
Key Concepts
- •Use a known molar mass to connect grams and moles.
- •Compare reactants with balanced coefficients, then check predicted and actual yield.
- •Separate concentration, dilution and reaction stoichiometry.
Prerequisites
Units and scientific notation
Keep mass, amount and volume units consistent.
Balanced chemical equations
Use mole ratios rather than comparing reactant masses directly.
1. Amount and mass
Use a known molar mass to connect grams and moles.
2. Reaction yield
Compare reactants with balanced coefficients, then check predicted and actual yield.
3. Solutions
Separate concentration, dilution and reaction stoichiometry.
Molarity Calculator
Calculate the molarity (molar concentration) of a solution from the number of moles of solute and the volume of solution in liters.
Concentration Calculator
Calculate mass concentration (g/L or mg/mL) from the mass of solute and the volume of solution.
Solution Dilution Calculator
Calculate stock solution volume and the idealized solvent amount for a target concentration and final volume using C₁V₁ = C₂V₂.
Titration Calculator
Calculate the unknown concentration of an acid or base from titration data using the equivalence-point relationship.
