Answer:
He will need to exerat a force of 30N
Explanation:
To solve this problem we will apply the ideal gas equations for which the product of pressure and volume is defined, as the equivalent between the ideal gas constant by the amount of matter and the temperature, mathematically this equation is described as

Here,
P = Pressure
V = Volume
R = Ideal gas Constant
T = Temperature
n = Number of molecules
The pressure is in atmospheres, and considering the units of the other values we have finally that,





Replacing,



Multiplying the number of moles by Avogadro's number we have,


Therefore the number of ozone molecules in the Earth's ozone layer are
