Question

Necesito resolver un cuadro de ecuaciones de estado
Con estas formulas en esta debo hallar tempreratura;
Formula; T= pv/nR
Datos;
P=640mm hg
V=1500 cm
T= ?
N= 1mol
En esta debo hallar moles
Formula;
N=pv/Rt
Datos:
P=5atm
V= 2l
T=300 °c
N= ?
En esta volumen
Formula v= NRT/P
Datos;
P=1200torr
V=?
T= 25°c
N= 6

Ayudenme porfavor :( ♡

Answer 1

a) Hallar temperatura

T = ?
P = 640 mmHg/760 = 0.84 at
V = 1500 cm³ = 1500 mL / 1000 = 1.5 L
R = 0.0821 (L atm / mol K)
n = 1 mol

P x V = n x R x T

T =       0.84 atm  x  1.5 L
      `````````````````````````````````````
     0.0821(L atm/mol K) x 1 mol

T = 15.35 K

b) Hallar moles

n = P x V
     `````````
      R x T

P = 5 atm
V = 2 L
T = 300 ºC + 273 = 573 K
R = 0.0821 (L atm / mol K)

n =           5 atm   x   2 L
     ``````````````````````````````````````
     0.0821(L atm/mol K) x 573K

n = 0.21 moles

c) V = ?

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

n = 6 moles
R = 0.0821 (L atm/mol K)
T = 25 ºC + 273 = 298 K
P = 1200 Torr
           1 torr ----- 0.001316 atmósferas
     1200 torr -----        x
 
              x = 1.58 atm

V = 6 moles x 0.0821 (L atm/mol K) x 298 K    
      ```````````````````````````````````````````````````````
                          1.58  atm

V = 92.90 L
