This relationship also extends to compounds. The formula mass of water, H2O, is 18.0 amu. If we take 18.0 grams of water then it should have the same number of molecules as there were atoms in 12.0 grams of carbon. The carbon-12 isotope.

It said that bottlenose dolphins have a brain mass of 1,500 to 1,700 grams, which is greater than that of humans (1,300 to.

To find the gram molecular mass or molar mass of a molecule, we keep the numerical value the same as the molecular mass, but simply change units as above from u to g. For example, as we have already calculated, molecular mass of water.
