Question

suponer que 0.248 moles de un gas ideal ocupan 9.23L a una presion de 0.63 atm ¿ cual es su temperatura en Celcius

Answer 1

Ley de los gases ideales

P  ·  V = n · R · T

R = 0.0821 (atm · L/ mol · K)
T = ?
n = 0.248 moles
P = 0.693 atm
V = 9.23 L

Calcular T =

T = V · P
     ````````
       R · n

T =              9.23 L  · 0.63 atm
        ``````````````````````````````````````````````
         0.0821(atm·L/mol·K) · 0.248 mol

T = 285.6 K

ºC = K - 273

ºC = 285.6 - 273 = 12.6 ºC
