The Ideal Gas Law for Pressure calculator computes the pressure (P) of a gas based on the temperature (T), volume (V) and number of moles (n) using the Ideal Gas Law and the universal gas constant (R) .
INSTRUCTIONS: Choose units and enter the following:
- (n) Moles (amount of substance or gas)
- (T) Temperature
- (V) Volume
Gas Pressure (P): The calculator returns the pressure in pascals (Pa). However, this can be automatically converted to compatible units via the pull-down menu.
The Math / Science
The ideal gas law is the equation of state of a hypothetical ideal gas. It is a good approximation to the behavior of many gases under many conditions. The ideal gas law is often represented in its common form:
where:
- P - pressure of the gas
- T - temperature of the gas
- n - amount of the gas, typically specified in moles (mol)
- V - volume of the gas
- R - universal gas constant
This calculator solves the Ideal Gas Law equation for pressure (P).
