STP Calculator
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.
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.
Osmotic Pressure Calculator
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.
Van't Hoff Factor Calculator
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.
