Calcular el volumen que ocupa 66 gramos de CO medido a 27°C y 624 mm Hg Dato: Masas atómicas: C= 12 y O=16 . R=62,4 mmHg L/mol K

Respuesta:

72 L

Explicación:

Paso 1: Calcular los moles de CO

La masa molar de CO es 28,01 g/mol.

Paso 2: Convertir la temperatura a Kelvin

Siempre que trabajamos con gases ideales, debemos convertir las temperaturas a la escala Kelvin. Usaremos la siguiente formula.

K = °C + 273,15

K = 27°C + 273.15

K = 300 K

Paso 3: Calcular el volumen de gas

Usaremos la ecuación del gas ideal

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
