Question

un gas ocupa un volumen de 520ml a 25°c y 650 mmHg de presion. calcula el volumen que ocuparia el gas a 700mmHg y °32c

Answer 1

V1 = 520 mL / 1000 = 0.520 L
T1 = 25 + 273 = 298 K
P = 650 mmHg
  1 atm --- 760 mmHg
     x     ---  650 mmHg
x = 0.85 atm

V2 = ?
T2 = 32 + 273 = 305 K
P = 700 mmHg
 1 atm --- 760 mmHg
    x     ---  700 mmHg
x = 0.92 atm

V1 P1 T2 = V2 P2 T1

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


V2 =  0.520 L  x  0.85 atm  x 298 K
        ``````````````````````````````````````````
                 0.92 atm x  305 K

V2 = 0.496 L

V2 = 496 mL
