<h3>What are iron ores?</h3>

Iron ores refers to minerals in which iron occur in combined form found in the earth's crust.

Some ores of iron include:

  • hematite,
  • magnetite,
  • limonite, and
  • siderite.

Molar mass of hematite, Fe₂O₃ = 160 g/mol

Molar mass iron = 56 g/mol

Percent mass of iron in hematite = 56/160 = 35%

The mass of hematite that contains 8.0×10³ kg of iron = 8.0 × 10³kg/0.35 = 2.29 × 10⁴ kg.

Therefore, the mass of hematite that contains 8.0×10³ kg of iron is 2.29 × 10⁴ kg.
