Chemical Formulas as Formulas: Converting between Grams of a Compound and Gram of a Constituent Element. 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.
States of Matter
The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
Chemical Reactions and Equations
When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.
