Understanding Molar Mass

Molar mass is a fundamental concept in chemistry that allows chemists to convert between the mass of a substance and the amount of substance (number of moles). This is crucial for stoichiometric calculations in chemical reactions.

How to Calculate Molar Mass

Step 1: Identify Elements

Break down the chemical formula into its constituent elements, including subscripts.

Step 2: Find Atomic Masses

Look up the atomic mass of each element from the periodic table.

Step 3: Multiply by Subscripts

Multiply each element’s atomic mass by its subscript in the formula.

Step 4: Sum All Values

Add together the masses of all elements to get the molar mass.

Example Calculation

For glucose: C₆H₁₂O₆

6 × C = 6 × 12.01 g/mol = 72.06 g/mol
12 × H = 12 × 1.01 g/mol = 12.12 g/mol
6 × O = 6 × 16.00 g/mol = 96.00 g/mol
Total = 72.06 + 12.12 + 96.00 = 180.18 g/mol
