The final pressure or the air pressure on the top of the mountain is 0.818.
Air pressure is the pressure exerted by air in the atmosphere of the earth.
By the Gas law
[tex]\dfrac{P_1V_1}{ T1} =\dfrac{ P_2V_2 }{T_2}[/tex]
Given, the pressure of the valley floor is 1 atm. = P1
The temperature is 25° C = T1
The volume of the bag is 0.985 L. = V1
The temperature at the top of the mountain is ° C = T2
Now, the volume of the bag is 1. 030 L = V2
To find P2
Put the values in the formula
[tex]\dfrac{1 atm \times0.985 L}{ 25} =\dfrac{ P_2 \times 1. 030 L }{22}\\\\0.03832 = 0.0468 \times P_2\\\\P_2= 0.818[/tex]
Thus, the final pressure is 0.818.
