Here are the essential concepts you must grasp in order to answer the question correctly.
Balancing Chemical Equations
Balancing chemical equations involves ensuring that the number of atoms of each element is the same on both sides of the equation. This is based on the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction. To balance an equation, coefficients are adjusted in front of the chemical formulas to achieve equal atom counts.

Molar Mass and Moles
The molar mass of a substance is the mass of one mole of that substance, typically expressed in grams per mole (g/mol). It is calculated by summing the atomic masses of all atoms in a molecule. Understanding moles is crucial for stoichiometric calculations, as it allows for the conversion between grams and the number of particles, facilitating the determination of reactant and product quantities in a reaction.

Stoichiometry
Stoichiometry is the quantitative relationship between reactants and products in a chemical reaction. It uses balanced equations to determine how much of each substance is needed or produced. By applying stoichiometric principles, one can calculate the required amounts of reactants, such as carbon in this case, based on the mass of the starting material, hematite.
