Chemistry Calculators (Page 4)
Concentration, molar mass, reactions and more chemistry tools.
Molar Mass Calculator
Enter a chemical formula; the tool instantly computes the molar mass M = Σ(atomic mass × atom count) from atomic weights, and also reports element composition and percentage by mass.
Theoretical Yield Calculator
Enter the limiting-reagent moles, the stoichiometric ratio (product coefficient / limiting-reagent coefficient) and the product molar mass; the tool instantly computes the product moles and theoretical mass.
Titration Calculator
Enter the known solution's concentration C₁ and volume V₁ and the unknown solution's volume V₂; at the equivalence endpoint (C₁V₁ = C₂V₂) the tool instantly computes the unknown concentration C₂.
Raoult's Law Calculator
Enter the solute mole fraction x and the pure-solvent vapor pressure P°; by Raoult's law ΔP = x·P° the tool instantly computes the vapor-pressure lowering and the solution vapor pressure.
Enthalpy of Reaction Calculator
Enter the standard enthalpy of formation ΔH_f for each reactant and product and their stoichiometric coefficients; using ΔH° = ΣΔH_f(products) − ΣΔH_f(reactants) the tool instantly computes the standard reaction enthalpy.
Volume Percent Calculator
Enter the solute volume and the total solution volume; by v/v% = solute volume / total solution volume × 100 the tool instantly computes the volume percent concentration.
Particles to Moles Calculator
Enter the particle count N (atoms, molecules or ions); using n = N / Nₐ (Nₐ = 6.022×10²³ /mol) the tool instantly computes the amount of substance in moles.
Nernst Equation Calculator
Enter the standard potential E°, electrons transferred n and reaction quotient Q; at 25 °C the Nernst equation E = E° − (0.0592/n)·log Q instantly gives the electrode (cell) potential.
Percent Ionization Calculator
Enter the ionized concentration (e.g. equilibrium [H⁺]) and the initial concentration C₀; using % = ionized/C₀ × 100 the tool instantly computes the percent ionization of a weak acid or weak base.
Specific Gravity Calculator
Enter the substance density and the reference density (water commonly 1000 kg/m³ or 1 g/mL); by SG = ρ_substance / ρ_reference the tool instantly computes the dimensionless specific gravity.
Mass/Volume Percent Calculator
Enter the solute mass (g) and solution volume (mL); using w/v% = mass/volume × 100 the tool instantly computes the mass/volume percent concentration.
Dalton's Law of Partial Pressures Calculator
Enter a gas mole fraction xᵢ and the total pressure P_total of the gas mixture; using Dalton's law Pᵢ = xᵢ × P_total the tool instantly computes that component's partial pressure.
