What is Molar Mass?

Molar mass is a fundamental concept in chemistry that refers to the mass of one mole of a substance. It is expressed in grams per mole (g/mol). The molar mass of a compound is calculated by summing the atomic masses of all the atoms in one molecule of the compound. For FeCl3, this involves knowing the atomic masses of iron (Fe) and chlorine (Cl).

Calculating the Molar Mass of FeCl3

To calculate the molar mass of FeCl3, we need to know the atomic masses of iron and chlorine. The atomic mass of iron (Fe) is approximately 55.845 g/mol, and the atomic mass of chlorine (Cl) is approximately 35.453 g/mol. Since there are three chlorine atoms in FeCl3, we need to multiply the atomic mass of chlorine by three.

Here is the step-by-step calculation:

Atomic mass of Fe: 55.845 g/mol
Atomic mass of Cl: 35.453 g/mol
Number of Cl atoms in FeCl3: 3

The molar mass of FeCl3 is calculated as follows:

Molar mass FeCl3 = (Atomic mass of Fe) + 3 × (Atomic mass of Cl)

Molar mass FeCl3 = 55.845 g/mol + 3 × 35.453 g/mol

Molar mass FeCl3 = 55.845 g/mol + 106.359 g/mol

Molar mass FeCl3 = 162.204 g/mol
