Question

CALCULAR LA MASA 0.2L DE CLORO MOLECULAR CL2 A3AT Y546 OK SI LA DESIDAD EN CONDICIONES NORMALES ES 3,17 G/L

Answer 1

Ley de los gases ideales

V x P = n x R x T

P = 3 atm
V = 0.2 L
R = 0.0821 ( Lx atm / mol  x  K)
T = 546 K
n = ?

n =             3 atm  x  0.2 L
     ```````````````````````````````````````````
    0.0821 (L x atm/mol x K) x 546 K

n = 0.0133 moles de cloro

2. calcular masa de Cloro molecular

Mm Cl2 = 35.45 g/mol x 2 = 70.9 g/mol

3. calcular masa de cloro molecular

masa = 0.0133 mol Cl2  x  70.9 g Cl2
                                           ```````````````
                                            1 mol Cl2

masa = 0.943 g de cloro molecular
