03. El óxido de magnesio (Mgo) es uno de los principales componentes en la fabricación de refractarios básicos, se obtiene a través del calentamiento del carbonato de magnesio
(MgCO3):
MgCO3() → MgO(s) + CO2(g)
Si se desea obtener 304 g de óxido de magnesio, ¿qué cantidad de carbonato de
magnesio con una pureza de 76% se deberá emplear?
