All tools
Ideal Gas Law Chemistry
Solve the ideal gas equation PV = nRT for pressure, volume, moles or temperature in atm, litres, mol and kelvin, with R = 0.082057 L·atm/(mol·K).
Vapor Pressure Calculator
Find the vapor pressure of water, ethanol, benzene or acetone at any temperature with the Antoine equation, shown in mmHg, kPa and atm.
Partial Pressure Calculator
Find a gas's partial pressure from its mole fraction and the total pressure, or from n, T and V. Results in kPa, atm, mmHg and bar with the working.
Boiling Point Elevation
Find how far a dissolved solute raises a solvent's boiling point from molality or masses, with Kb values for water, benzene, ethanol and four more.
