d = P×MM
R×T
donde P = presion (atm)
MM = masa molecular del gas ( g/mol),
R = constante de los gases ideales (atm·L/K·mol)
T = temperatura (ºK).
MM del H₂S = (1ₓ2) + (32ₓ1) = 34 g/mol
830 mmHg ₓ 1 atm = 1,09 atm
760 mmHg
ºK = ºC + 273º
ºK = 27º + 273º
ºK = 300
R = 0,0821 (atm·L/ºK·mol)
d = P×MM ⇒ 1,09 atm × 34 g/mol ⇒ 37,06 g ⇒ 1,5 g/L
R×T 0,0821 atm.L × 300ºK 24,63 L
