Understanding Molar Mass
Molar mass, also known as molecular weight, is a fundamental concept in chemistry. It represents the mass of one mole of a substance, expressed in grams per mole (g/mol). Molar mass is a crucial property used to determine the amount of a substance present in a given sample and to perform various stoichiometric calculations.
To calculate the molar mass of a compound, we add the atomic masses of all the atoms present in its chemical formula. The atomic mass of each element can be found in the periodic table. For example, the molar mass of water (H2O) is:
Molar mass of H2O = 2(1 g/mol) + 1(16 g/mol) = 18 g/mol
Practice Problems
1. Calculate the molar mass of sodium chloride (NaCl).
2. Determine the molar mass of glucose (C6H12O6).
3. Find the molar mass of calcium carbonate (CaCO3).
