Oxygen (O) has an atomic mass of about 16.00 amu. CO 2 has one carbon atom and two oxygen atoms. The molar mass of carbon dioxide is 12.01 + (2 × 16.00) = 44.01 g/mol.

Calculate molar mass of each element: multiply the atomic mass of each element by the number of atoms of that element in the compound. Add them together: add the results from step 3 to get the total molar mass of the compound. Carbon (C) has an atomic mass of about 12.01 amu. Oxygen (O) has an atomic mass of about 16.00 amu.

Calculate the molar mass of H2O in grams per mole or search for a chemical formula or substance.

2023年1月11日 · To calculate the atomic mass of water (H2O): Atomic mass of H2O = 2 × (Atomic mass of H) + (Atomic mass of O) = 2 × 1.008 amu + 16.00 amu = 2.016 amu + 16.00 amu = 18.016 amu. Therefore, the atomic mass of water (H2O) is …
