¿ que presión, expresada en mm de hg ejercen 0.4 moles de un gas ideal que ocupa 4 litros de volumen a una temperatura de -25 °C
R = 0.0821 (l x atm / mol K)
T = -25 + 273 = 248 K
V = 4 L
n = 0.4 moles
P x V = n x R x T
P = n x R x T
`````````````````
V
P = 0.4 moles x 0.0821 (L x atm / mol x K) x 248 K
``````````````````````````````````````````````````````````````````
4 Litros
P = 2.036 atm
1 atm ----- 760 mmHg
2.036 atm ----- x
x = 1547,36 mmHg
