User Guide

This tool will calculate any parameter from the equation defined by Avogadro’s law, which includes  the V1 gas volume, n1 amount of gas, V2 gas volume and n2 amount of gas.

Avogadro’s law states that equal volumes of different gases contain an equal number of molecules, if they have the same temperature and pressure. For an ideal gas, the volume of the gas is directly proportional to the amount of gas, as long as the pressure and temperature of the gas remains constant.

Formulas

Avogadro’s Law is explained with math in the following ways.

The volume of an ideal gas is proportional to the amount of gas:

V ∝ n

The volume divided by the amount of gas in a given state, equals a constant value:

V / n = Constant

The division of volume by the amount of ideal gas in one state or of one sample, equals the division of volume by the amount of ideal gas in another state or of another sample, as long as the pressure and temperature does not change between the two states or two samples.

V1 / n1 = V2 / n2

The formulas used by this Avogadro’s law calculator to determine each individual parameter are:

V1 = V2 · n1 / n2

n1 = n2 · V1 / V2

V2 = V1 · n2 / n1

n2 = n1 · V2 / V1

Symbols

  • V1 = Volume of the first gas state/sample
  • n1 = Amount of the first gas state/sample
  • V2 = Volume of the second gas state/sample
  • n2 = Amount of the second gas state/sample

V1

This is the total volume occupied by the first gas state or sample.

n1

This is the amount of the first gas state or sample.

V2

This is the total volume occupied by the second gas state or sample.

n2

This is the amount of the second gas state or sample.
