Question

calcula la densidad del gas metano CH4en g/l a25 centigrados y 0.978atm

Answer 1

P V = n R T     ley de gases ideales

T = 25 ºC + 273 = 298 K

P = 0.978 atm

R = 0.0821 (atm.L / K mol
d = masa/volumen d=m/V

Mol = masa/Mm;  Mm = masa/mol                                  sustituir                              d  = P  x  Mm ÷  R x T                          

d =      0.978 atm x  16 g/mol

       0.0821(Latm/molK) x 298 K

d = 0.6395 g/L
