Question

1. Un gas ocupa un volumen de 520 ml a 25°C y 650 mmhg de presión, Calcula el volumen que ocuparía el gas 700 mmhg y 32°C.

Answer 1

LEY general de los gases

V1  P1 = V2 P2
`````````   ``````````
    T1         T2

Datos:
V1 = 520 mL/ 1000 = 0.50 l
P1 = 650 / 760 = 0.86 atm
T1 = 25 + 273 = 298 K
V2 = ?
T2 = 32 + 273 = 305 K
P2 = 700 /760 = 0.92 atm

calcualr V2

V2 =  V1  x  P1  x T2
        ```````````````````````        
               P2  x  T1

V2 = 0.520 L  x  305K  x  0.86 atm
       ````````````````````````````````````````
               0.92 atm  x  298 K

V2 = 0.498 L

V2 = 0.498 X 1000 = 498 mL
