To find the molar mass of complex compounds, just follow these easy steps:
Identify Elements: First, look at the chemical formula. Write down all the elements you see.
Count Atoms: Next, figure out how many atoms of each element are in the formula.
Use Atomic Masses: Then, check the periodic table to find the atomic mass of each element.
Calculate: Multiply the atomic mass by how many atoms of that element you have.
Finally, add up all the numbers to get the total molar mass!
For example, let's see how it works with water, which has the formula H₂O:
For hydrogen (H):
1.01 g/mol × 2 = 2.02 g/mol
For oxygen (O):
16.00 g/mol × 1 = 16.00 g/mol
Now, add them together:
Total = 2.02 + 16.00 = 18.02 g/mol.
See? It’s that simple!
