Question

Cierto gas tiene un volumen de 205 ml a 20°c y 1.00 atm ¿ Cual es su volumen en ml a 69°c y 600mm hg?

Answer 1

LEY GENERAL DE LOS GASES:

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

V1 = 205 mL / 1000 = 0.205 L
P1 = 1.00 atm
T1 = 20 ºC + 273 = 293 K

V2 = ?
P2 = 600 mmHg / 760 = 0.789  atm
T2 = 69 ºC + 273 = 342 K

V2 = P1 · V1 ·  T2
         ``````````````````
            V2 · T1

V2 = 1.00 atm · 0.205 mL · 342 K
         ````````````````````````````````````````
                  0.789 atm. 293 K

V2 = 0.3032 L
