Calculate the molar mass for each of the following:c. Fe(ClO₄)₃

Verified step by step guidance

1. Identify the elements in the compound Fe(ClO_4)_3: Iron (Fe), Chlorine (Cl), and Oxygen (O).
2. Determine the number of each type of atom in the compound: 1 Fe, 3 Cl, and 12 O (since there are 3 ClO_4 groups, each containing 1 Cl and 4 O).
3. Find the atomic masses of each element from the periodic table: Fe = 55.85 g/mol, Cl = 35.45 g/mol, O = 16.00 g/mol.
4. Calculate the total mass contributed by each element: Fe = 1 * 55.85 g/mol, Cl = 3 * 35.45 g/mol, O = 12 * 16.00 g/mol.
5. Add the masses of all the elements to find the molar mass of Fe(ClO_4)_3.

Key Concepts

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. Understanding molar mass is essential for converting between grams and moles, which is a fundamental concept in stoichiometry.

Chemical Formula

A chemical formula represents the composition of a compound, indicating the types and numbers of atoms present. In the case of Fe(ClO₄)₃, the formula shows that there is one iron (Fe) atom and three perchlorate (ClO₄) groups. Recognizing how to interpret chemical formulas is crucial for calculating molar mass accurately.

Atomic Mass

Atomic mass is the weighted average mass of an element's isotopes, measured in atomic mass units (amu). It is listed on the periodic table and is used to determine the contribution of each element in a compound to the overall molar mass. Knowing the atomic masses of the constituent elements is vital for performing molar mass calculations.
