To find the molar mass of a compound, you can follow these simple steps:

1. Find the Chemical Formula: First, identify the formula of the compound. For example, water is written as (H_2O).

2. Look Up Atomic Masses: Use the periodic table to check the atomic mass of each element.

   Here’s an example:

   • Hydrogen (H): about 1.01 g/mol
   • Oxygen (O): about 16.00 g/mol

3. Count the Atoms: Next, count how many atoms of each element are in the formula.

   • For (H_2O): There are 2 hydrogen (H) atoms and 1 oxygen (O) atom.

4. Do the Math: Now, multiply the atomic masses by the number of atoms you counted, then add them together.

   Here’s how it works for (H_2O):

   • For hydrogen: (2 \times 1.01) g/mol = 2.02 g/mol
   • For oxygen: (1 \times 16.00) g/mol = 16.00 g/mol
   • Total: (2.02 + 16.00 = 18.02) g/mol

5. Final Answer: So, the molar mass of water is 18.02 g/mol.
