Question

que volumen ocuparán 15g de Ar a 200 F y 735 mmhg​

Answer 1

que volumen ocuparán 15 g de Ar a 200 F y 735 mmHg​

Aplicar la ley de los gases ideales

V x P = n x R x T

Datos:

R = 0.0821 (L atm / mol K)

P = 735 mmHg / 760 = 0.967 atm

T =200 F

1. convertir ºF a ºC

ºC = (ºF - 32) / 1.8

ºC = (200 - 32) / 1.8

ºC = 93.33

2. Convertir ºC a K

K = ºC + 273

K = 93.33 + 273

K = 366.33

3. calcular moles de argón

Mm Ar = 39.94 g/mol

n = masa/Mm

n = 15 g / 39.94 g/mol

n = 0.376 moles

4. Calcular Volumen

V = (n x R x T) / P

V = ( 0.376 moles x 0.0821 (L atm / mol K) x 366.33 K) / 0.967 atm

V = 11.69 Litros
