Answer:
The answer to your question is P2 = 2.64 atm
Explanation:
Data
Volume 1 = 2.35 L
Temperature 1 = 122°C
Pressure 1 = 1.78 atm
Volume 2 = 1.15 L
Temperature 2 = 14°C
Pressure 2 = ?
Process
To solve this problem use the combined gas law.
P1V1/T1 = P2V2/T2
-Solve for P2
P2 = P1V1T2/T1V2
1.- Convert temperature to °K
Temperature 1 = 122 + 273 = 395°K
Temperature 2 = 14 + 273 = 287°K
2.- Substitution
P2 = (1.78 x 2.35 x 287) / (395 x 1.15)
3.- Simplification
P2 = 1200.521 / 454.25
4.- Result
P2 = 2.64 atm
