3. Multiply by Subscript: For each element, multiply its atomic weight by the number of atoms of that element in the formula.
4. Add Together: Sum the total mass contributions from each element to get the total molar mass of the compound.

Example Calculation

Let’s consider a compound like water (H₂O). Here’s how you calculate its molar mass:

• Hydrogen (H) has an atomic mass of 1.008 g/mol. Since there are 2 hydrogen atoms, we multiply 1.008 by 2: 2.016 g/mol.
• Oxygen (O) has an atomic mass of 16.00 g/mol. There is 1 oxygen atom, so it remains 16.00 g/mol.

Now, add these together: 2.016 g/mol + 16.00 g/mol = 18.016 g/mol for the molar mass of water.

Once you have the molar mass, you can use it to convert between grams and moles, which is necessary for solving various problems related to chemical reactions.
