Answer 1

Respuesta:

n = 0.714 moles de gas HELIO

Explicación:

Calcule el número de moles de gas helio 16.0​ L

        1 mol ---- 22.4 L

             x   ---- 16.0 L

              x = 0.714 mol de gas Helio

Aplicar Ley de los gases ideales

V x P = n x R x T

V = 16.0 L

P =  1 satm

n = ¿?

R = 0.0821 (L atm / mol K)

T = 273.15 K

n = ( 16.0 L x 1 atm) / ( 0.0821 (L atm / mol K) x 273.15 K)

n = 0.714 moles de gas HELIO
