We are asked to calculate the mass percent composition of iron for FeCO_{3} (siderite).

Molar mass Fe = 55.85 g/mol

Molar mass FeCO_{3} = 115.86 g/mol

Iron is mined from the earth as iron ore. Common ores include Fe_{2} O_{3} (hematite), Fe_{3} O_{4} (magnetite), and FeCO_{3} (siderite).

Calculate the mass percent composition of iron for FeCO_{3} (siderite).
