Correct statement in the following

Pressure of the gas is defined as the force exerted by the particles on the walls of the container. S.I unit of pressure is pascal.

We are given:

Pressure = 1.0 Pascal

mass = x mg =    

Area =

In fact, a 1 m² column of air extending from the Earth's surface through the upper atmosphere has a mass of about 10,300 kg, producing an atmospheric pressure of approximately 101,000 Pa, or 101 kPa

The SI unit of pressure is pascal (represented as Pa) which is equal to one newton per square metre (N/m² or kg m^-1s^-2).
