The gas constant also well-known as the molar, universal, or ideal gas constant, represented by the symbol R. Use ideal gas law calculator on the top check the bellow results. Substitute the specified values in the equation: Examples on Ideal Gas Law Calculator with StepsĮxample 1: Ideal gas law solve for moles, pv=nrt solve for n:įind the number of moles at 300K temperature, 250kPa pressure and 5 liters volume? State the equation you plan to use and plug in the values.

Ideal Gas Law for Number of Moles of Gas(n) = PV / RT.

Ideal Gas Law for Temperature(T) = PV / nR.

Ideal Gas Law for Pressure(P) = nRT / V.

ĭifferent Ideal Gas Law Equations for different unknown (our PV=nRT calculator is based on the below equation): Value R, Gas Constant units Pressure Units Volume Unit Temperature 8.20578 X 10 -2 L atm K -1 mol -1 atm Litres, L K 8.31451 X 10 -2 L bar K -1 mol -1 Bar Litres, L K 8.314 J K -1 mol -1 Pa or Nm -2 cm 3 K 1.987 cal K-1 mol-1 Pa or Nm -2 cm 3 K PV=nRT Units PV=nRT Calculator with Steps. The unit of pressure times volume are the units of energy, example joules is equal to Pa m3. if you want to use the PV=nRT in different check the below table or convert to the right unit (or simply use the online ideal gas law calculator on the top). In SI units, P in pascals, V in cubic metres, n in moles, T in kelvins and R has the value 8.314 J/(K To make sure that we are using the ideal gas law correctly, we should have PV=nRT at the right units. and high temperature well above the boiling temperature.

In other simple words the ideal gas law applied at low low pressure ( few atmos).

The temperature of the gas is proportional to the average kinetic energy of the molecules.

Collisions between particles and between particles and the container walls are elastic collisions.The gas particles are small compared with the distance separating them.There are no attractive forces between gas particles.Gas particles are in continuous, rapid, random motion.The ideal gas law applies only to ideal gas which is define by the below assumption: The ideal gas law was stated by Emile Clapeyron which is equation of state relating state variable such as volume, temperature and pressure at given set of physical conditions.

The ideal gas law is an equation of state and comprise the Boyle’s Law, Charles’s Law and Avogadro’s Law into a single statement.
