Question

calcula la presion de 2 moles de gas helio en un recipiente de 10l a27ºC

Answer 1

Ley de los gases ideales:  V · P  = n · R · T
V = 10 L
P =  atm.
T = 27 ºC + 273 = 300 K
n = 2 moles
R = 0.0821 (L atm / mol K)

  P = 2 moles · 0.0821 (L atm/mol K) · 300 K

                                   10 L

P = 4.926 atm
