Se combustionan 2 g de magnesio en Aire, obteniéndose 3,28 g de óxido de magnesio (MgO)¿Qué masa de oxígeno se consumen en la re
konstantin123 [22]

Answer:

1.30 g

Explanation:

La reacción que toma lugar es:

  • 2Mg + O₂ → 2MgO

Primero <u>convertimos 3.28 g de MgO en moles</u>, usando su <em>masa molar</em>:

  • 3.28 g ÷ 40.3 g/mol = 0.081 mol MgO

Después <u>convertimos 0.081 moles de MgO en moles de O₂</u>, usando los <em>coeficientes estequiométricos</em>:

  • 0.081 mol MgO * \frac{1molO_2}{2molMgO} = 0.0407 mol O₂

Finalmente<u> convertimos 0.0407 moles de O₂ en gramos</u>:

  • 0.0407 mol O₂ * 32 g/mol = 1.30 g
