Iron is found in Earth's crust as several iron compounds. Calculate the mass (in kgkg) of each compound that contains 7.1×103 kg of iron. Given: Fe2O3 (hematite) Express your answer in kilograms to two significant figures. The answer : Mass = 1.1 x 104 kg But I don't know how it got here. I keep getting 4.9 kg for my answer. Converted it to kilograms also is a challenge for me. I know that 1 g = 1000 kg and that 1 kg = 0.001 g. But i'm not sure how to apply it.
