Answer:

78.084%

Step-by-step explanation:

a) ¿Qué porcentaje (%) del componente atmosférico representa el nitrógeno?

Se nos dice que:

La atmósfera en estado puro está compuesta por 20.946% de oxígeno, 0.934% de argón, 0.036% de trazas y el resto de nitrógeno.

Deje que el contenido total de la atmósfera se represente como: 100%

Por lo tanto:

100% = 20.946% + 0.934% + 0.036% + nitrógeno

1 = 0.20946 + 0.00934 + 0.00036 + nitrógeno

1 = 0.21916 + nitrógeno

Nitrógeno = 1 - 0.21916

Nitrógeno = 0.78084

Convertir a porcentaje = 0.78084 × 100

= 78.084%
