Calculators

Estimates the cost of building a shed, considering size and roof type.

Calculates the number of balusters needed for a railing based on the railing length and the desired baluster spacing.

Calculates the actual yield of a chemical reaction, given the theoretical yield and percent yield.

Calculates the required volume of diluent to add to a dry ingredient (drug) to achieve a desired concentration, and the resulting mass of the drug in a given volume.

Calculates the dilution factor, final volume, initial volume, or final concentration based on the given inputs. Dilution is the process of reducing the concentration of a solute in a solution, usually simply by mixing with more solvent.

This calculator helps you convert between different concentration units, including molarity (mol/L) and percentage concentration (% w/v, % v/v, % w/w).

Calculates the activity coefficient of an ion in a solution using the Debye-Hückel equation or its extended versions.

Converts parts per million (ppm) to molarity (mol/L) for solutions. This calculation requires the solute's molecular weight and the solution's density.

Calculates the mole fraction of a substance in a mixture using two different methods: either by providing the number of moles of each substance or by providing the mass of each substance and their respective molar masses.

Calculates the percentage by mass of each element in a chemical compound.
