Answer:

cuantos gramos de acido sulfúrico se necesitan para preparar una solucion 0,6 m de k2so4?

is D. 0.60 L.

Explanation:

Explicación:

Para la neutralización ácido-base, tenemos el papel:

El no. de milimoles de ácido es igual al de la base en la neutralización.

∴ (XMV) NaOH = (XMV) H₂SO₄.

X es el no. de H⁺ reproducible (para ácido) u OH⁻ (para base),

M es la molaridad.

V es el volumen.

Para NaOH:

X = 1, M = 4.0 M, V = ??? L.

Para H₂SO₄:

X = 2, M = 4.0 M, V = 0.3 L.

∴ V de NaOH = (XMV) H₂SO₄ / (XM) NaOH = (2) (4.0 M) (0.3 L) / (1) (4.0 M) = 0.6 L.

Entonces, la elección correcta es: D. 0.60 L.
