Question

calcula el número de moles de gas helio en 16.0 l​

Answer 1

Respuesta:

x = 0.714 mol de Helio

Explicación:

calcula el número de moles de gas helio en 16.0 l​

          1 mol ---- 22.4 L

              X  - --- 16.0 L

                  x = 0.714 mol de Helio

Aplicar ley de los gases ideales

V x P = n x R x T

V = 16.0 L

P = 1 atm

n = ¿?

R =  0.0821 (L atm / mol K)

T = 273.15 K

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

n = 0.714 mol de gas Helio
