Calculators
Create and discover interactive calculators for various scenarios and measurements.
Osmolarity Calculator
Calculates the osmolarity of a solution based on the molar concentration of solutes.
Rate Constant Calculator
Calculates the rate constant (k), reaction rate, or substance concentration using the rate law equation.
Molarity Calculator
Calculates the molarity of a solution given the number of moles of solute and the volume of the solution in liters. Also calculates mass from molarity, volume and molecular weight.
Percentage Concentration to Molarity Calculator
Converts percentage concentration of a solution to molarity, given the density and molecular weight of the solute.
Melting Point Calculator
Calculates the melting point of a substance based on the provided pressure. This calculator uses a simplified model and is most accurate for substances with well-defined melting points. Note: This calculator provides estimations and should not be used for critical applications.
Ideal Gas Law Calculator
Calculates pressure, volume, temperature, or the number of moles of an ideal gas using the Ideal Gas Law: PV = nRT. Where P = pressure, V = volume, n = number of moles, R = ideal gas constant, and T = temperature.
Combined Gas Law Calculator
Calculates the relationship between pressure, volume, and temperature of a gas using the combined gas law: (P1 * V1) / T1 = (P2 * V2) / T2. This calculator allows you to solve for any one of these variables, given the others.
Molecular Weight Calculator
Calculates the molecular weight (also known as molar mass) of a chemical compound based on the sum of the atomic weights of each element in the molecular formula.
pKa Calculator
Calculates the pKa value of a solution using either the Henderson-Hasselbalch equation or the acid dissociation constant (Ka).
Boiling Point Elevation Calculator
Calculates the boiling point elevation of a solution using the ebullioscopic constant, molality, and van't Hoff factor.
