The force of all gas particle/wall collisions divided by the surface area of the wall is the definition of pressure (P): One of the fundamental quantifiable variables of this phase of matter, pressure, is a property shared by all gases.
The force delivered perpendicularly to an object's surface per unit area across which that force is dispersed is known as pressure. In comparison to the surrounding pressure, gauge pressure is the pressure. Pressure is expressed using a variety of units.

490mmHg (1 atm/760 mmHg)=0.6447368421 atm
520 torr (1 mmHg/1 torr)(1 atm/ 760 mmHg)=0.6842105263 atm
P(He)+P(N)+P(Ne)=P(total)
0.6447368421+0.75+0.6842105263=2.078947368 atm
2.08 atm
