WebChemists defined the molar masses of elements such that a mole of atoms of a single element would be equal to its atomic mass, but in grams instead of u. So carbon's relative atomic mass is 12.01 u, but a mole of carbon atoms is 12.01 gram simply because we defined it to be so. Hope that helps.

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. WebThe molar amounts of carbon and oxygen in a 100-g sample are calculated by dividing each element’s mass by its molar mass: 27.29 g C ( mol C 12.01 g ) = 2.272 mol C 72.71 g O ( … healthy weight for 5ft 10 male
