Answer:
The answer to your question is P2 = 280 mmHg
Step-by-step explanation:
Data
Pressure 1 = P1 = 400 mmHg
Volume 1 = V1 = 1.75 L
Pressure 2 = ?
Volume 2 = 2.5 L
Process
1.- Use Boyle's law to solve this problem
P1V1 = P2V2
-Solve for P2
P2 = P1V1 / V2
2.- Substitution
P2 = (400)(1.75) / 2.5
3.- Simplification
P2 = 700 / 2.5
4.- Result
P2 = 280 mmHg
