Question

A gas is at temperature 80°c and pressure 5x10-10Nm-2.What

is the number of molecules per m3

if Boltzmann’s constant is

1.38 ×10-23JK-1.​

Answer 1

The ideal gas law can be written in terms of the number of molecules of gas: PV = NkT, where P is pressure, V is volume, T is temperature, N is number of molecules, and k is the Boltzmann constant k = 1.38 × 10–23 J/K. A mole is the number of atoms in a 12-g sample of carbon-12.
