Respuesta:
V2 = 21.37 L
Explicación:
Aplicar Ley general de los gases
V1 x P1 = V2 x P2
`````````````````` ```````````````````
T1 T2
Datos:
V1 = 8 L
T1 = 25 ºC + 273 = 298 K
P1 = 760 mmHg / 760 = 1 atm
V2 = ¿?
T2 = 125 ºC + 273 = 398 K
P2 = 380 mmHg / 760 = 0.5 atm
calcular V2
V2 = ( V1 x P1 x T2) / (P2 x T1)
V2 = ( 8 L x 1 atm x 398 K) / ( 0.5 atm x 298 K)
