WebDec 19, 2024 · The atomic mass of hydrogen is 1.008 g/mol and the atomic mass of oxygen is 16.00 g/mol. Since there are two atoms of hydrogen and one atom of oxygen in water, we must multiply 1.008 by 2, and then add that product to 16.00. This is how you can calculate the molar mass of water: 18.02 g/mol! 🥳. WebFor example, the molar mass of water (H2O) is 18 g/mol because the atomic mass of hydrogen (H) is 1 g/mol and the atomic mass of oxygen (O) is 16 g/mol. Molar mass is an important concept in chemistry because it allows for the conversion of mass to moles and vice versa. This is particularly useful when conducting chemical reactions.
