How to find molar mass of H2O?
Understand the Problem
The question is asking for the method to calculate the molar mass of water (H2O), which involves adding the atomic masses of its constituent elements, hydrogen and oxygen.
Answer
18 g/mol
The final answer is 18 g/mol.
Answer for screen readers
The final answer is 18 g/mol.
More Information
Water's molar mass is derived by considering the contributions of its hydrogen and oxygen atoms. Each hydrogen atom has an atomic mass of about 1 g/mol, and oxygen has an atomic mass of about 16 g/mol, leading to a total for H2O of 18 g/mol.
Tips
One common mistake is not using the correct number of atoms for each element in the molecular formula. Be sure to multiply the atomic mass by the number of atoms present in the molecule.
