Question

Dados 1000 mL de helio a 15°C y 763 mmHg, determinese su volumen a - 6°C y 420 mmHg. Resp. 1.68 × 10 mL

Answer 1

Respuesta:

P1  V1  = P2  V2

``````````    ``````````

  T1              T2

V2 = P1  V1  T2

        ```````````````

          P2 T1

V1 = 1000 mL = 1 L

P1 = 763 mmHg/760 = 1.004 atm

T1 = 15 + 273 0 288 K

V2 = ?

P2= 0.552 atm

T2 = -6 + 273 = 267 K

V2 = 1.004 atm  x  1 L  x  267 K

        ``````````````````````````````````````

             0.552 atm  x 288 K

V2 = 1.6862 L  x 1000 =  1.6862  x 10³ mL
