One method to synthesize ionic solids is by the heating of two reactants at high temperatures. Consider the reaction of FeO with TiO₂ to form FeTiO₃. Determine the amount of each of the two reactants to prepare 2.500 g FeTiO₃, assuming the reaction goes to completion. (b) Calculate the formula weight of FeTiO₃.

Calculate the molar mass of FeTiO3 by adding the atomic masses of Fe, Ti, and O (3 times) from the periodic table.

Determine the number of moles of FeTiO3 needed by dividing the given mass (2.500 g) by the molar mass of FeTiO3.

Write the balanced chemical equation for the reaction: FeO + TiO2 -> FeTiO3.

Use stoichiometry to find the moles of FeO and TiO2 required, based on the balanced equation and the moles of FeTiO3 calculated.

Convert the moles of FeO and TiO2 to grams using their respective molar masses to find the mass of each reactant needed.

주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Stoichiometry

Stoichiometry is the branch of chemistry that deals with the quantitative relationships between the reactants and products in a chemical reaction. It allows chemists to calculate the amounts of substances involved in a reaction based on balanced chemical equations. Understanding stoichiometry is essential for determining how much of each reactant is needed to produce a desired amount of product, such as FeTiO3 in this case.

Molar Mass

Molar mass is the mass of one mole of a substance, typically expressed in grams per mole (g/mol). It is calculated by summing the atomic masses of all the atoms in a chemical formula. For the synthesis of FeTiO3, calculating the molar mass is crucial for converting between grams of the compound and moles, which is necessary for stoichiometric calculations.

Chemical Reaction Completion

The concept of reaction completion refers to the assumption that a chemical reaction proceeds to completion, meaning that all reactants are converted into products without any leftover. This is important in stoichiometric calculations, as it simplifies the process by allowing the use of the full amount of reactants to determine the product yield. In the context of the question, it implies that the entire 2.500 g of FeTiO3 is produced from the reactants FeO and TiO2.
