Claire Lamb · Answer 1

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
