<h3>Answer:</h3>

0.95 atm

<h3>Explanation:</h3>

We are given;

Initial pressure, P1 = 1.0 atm

Initial temperature, T1 =298 K (25°C + 273)

Initial volume, V1 = 0.985 L

Final temperature, T2 = 295 K (22°C + 273)

Final volume, V2 = 1.030 L

We are required to find final air pressure;

Using the combined gas law;

\frac{P1V1}{T1} =\frac{P2V2}{T2}

To get, P2 ;

P2=\frac{P1V1T2}{T1V2}

P2=\frac{(1.0)(0.985L)(295)}{(1.030)(298)}

P2 = 0.947 atm

        = 0.95 atm

Therefore, the air pressure at the top of the mountain is 0.95 atm
