Question

Calcular los kg de O3 que tiene el gas a -5°c, 850 mmhg y 5505 ml

Answer 1

Mm O3 = 48 g/mol

t = -5 + 273 = 268 K

P = 850 mmHg

1 atm ------- 760 mmHg
     x    ------ 850 mmHg
x = 1.118 atm.

R = 0.0821 (atm L / mol K)

P x V  = n x R x T

n = P x  V
     ``````````
       R x T

n = 1.118 atm x 5.505 L
     ``````````````````````````````
   0.0821 (atm L / mol K) x 268

n = 0.2797 mol

n = masa/Mm

masa = n x Mm

masa = 0.2797 mol x 48 g/mol

masa = 13.42 g

Kg = 13420
