Supongo que quiere preparar una solución al 10% de sulfato de magnesio en peso. El frasco del producto químico que se tiene indi
Darina [25.2K]

Answer:

Se requerirán 14.57 gramos de MgSO₄·7H₂O, que se disolverían en 105.43 gramos de agua.

Explanation:

Si tenemos 120 gramos de una solución al 10% de sulfato de magnesio en peso, habrán en la solución (120*10/100) 12 gramos de sulfato de magnesio (MgSO₄).

Sin embargo, el reactivo que está disponible es heptahidratado (MgSO₄·7H₂O), por lo que hay que calcular <em>cuántos gramos de sulfato de magnesio heptahidratado contendrán 12 gramos de MgSO₄</em>.

<u>Calculamos las moles de 12 gramos de MgSO₄</u>, usando su masa molecular:

  • 12 g MgSO₄ ÷ 120.305 g/mol = 0.0997 mol MgSO₄.

<u>Después calculamos la masa de MgSO₄·7H₂O que contendrá 0.0997 mol MgSO₄</u>, usando la masa molecular de MgSO₄·7H₂O:

  • 0.0997 mol * 246.305 g/mol = 14.57 g MgSO₄·7H₂O

Para saber la cantidad de agua en la que se disolverá el reactivo, restamos la masa de soluto de la masa total de la solución:

  • 120 g - 14.57 g = 105.43 g

Write the net ionic equation for the following molecular equation Mg (s) +Snso (aq) Mgso4 (aq) Sn(s) Use the lowest possible coe
Simora [160]

Answer:

Mg(s) + Sn²⁺(aq) ⇄ Mg²⁺(aq) + Sn(s)

Explanation:

Let's consider the following molecular equation.

Mg(s) + SnSO₄(aq) ⇄ MgSO₄(aq) + Sn(s)

The full ionic equation includes al the ions and the species that do not dissociate in water.

Mg(s) + Sn²⁺(aq) + SO₄²⁻(aq) ⇄ Mg²⁺(aq) + SO₄²⁻(aq) + Sn(s)

The net ionic equation includes only the ions that participate in the reaction (not spectator ions) and the species that do not dissociate in water.

Mg(s) + Sn²⁺(aq) ⇄ Mg²⁺(aq) + Sn(s)
