Calculators

Calculates pressure, volume, number of moles, or temperature using the Ideal Gas Law: PV = nRT. This calculator assumes ideal gas behavior.

Calculates the compressibility factor (Z) for a real gas, indicating its deviation from ideal gas behavior.

Calculates the volume or number of moles of a gas at Standard Temperature and Pressure (STP). STP is defined as 0°C (273.15 K) and 1 atm pressure. This calculator uses the ideal gas law to perform these calculations.

Calculates the reaction quotient (Q) to determine the direction a reversible reaction will shift to reach equilibrium.

Calculates the Van't Hoff factor (i), which represents the number of particles a solute dissociates into in a solution. This factor is important in colligative properties calculations.

Calculates the ionic strength of a solution based on the concentrations and charges of the ions present.

Calculates the osmotic pressure of a solution using the van't Hoff equation. Osmotic pressure is the minimum pressure which needs to be applied to a solution to prevent the inward flow of water across a semipermeable membrane.

Calculates the heat of combustion (energy released) from a combustion reaction given the mass of the substance burned and its specific heat of combustion.

Calculates the molar ratio between two substances in a balanced chemical equation.

Calculates the boiling point of a substance at a given pressure using the Clausius-Clapeyron equation.
