A 8.60 L tank of nitrogen gas at a pressure of 455 mmHg is connected to an empty tank with a volume of 5.35 L. What is the final pressure in the system after the valve connecting the two tanks is opened? Assume that the temperature is constant.

Answer:

The final pressure in the system is 731,4 mmHg

Explanation:

To solve the unknown we apply Boyle's Law for gases where keeping the amount of gas and temperature constant, the relationship between pressure and volume from one state to another is:

P1 . V1 = P2 . V2

(8,60L . 455mmHg) = P2 . 5,35L

(8,60L . 455mmHg) / 5,35 L = P2

731,40 mmHg = P2
