I presume you mean the number density of air particles. If the number of particles per volume is N, the pressure P is related to N and temperature, T via

P = N k T

where k is Boltzmann's constant. Pressure is related to the number of particles, since the more particles the more collisions, and is related to temperature, since the higher the temperature the greater the average kinetic energy of the particles so that there will be more frequent and more energetic collisions.
