Various iron ores have different amounts of iron per kilogram of ore. Calculate the mass percent composition of iron for each iron ore: Fe2O3(hematite), Fe3O4(magnetite), FeCO3(siderite). Which ore has the highest iron content

Respuesta :

Answer:

Fe3O4(Magnetite)

Explanation:

The mass percent composition of iron for Fe2O3(hematite):

% Fe = 111.70g/159.70g X 100% = 69.944%

The mass percent composition of iron for Fe3O4(magnetite):

72.359%

The mass percent composition of iron for FeCO3(siderite):

48.203%

Thus, Magnetite ore Fe3O4 has the highest iron content i.e. 72.359%
