![]() The molar mass of a compound is the mass in grams of 1 mole of that substance, a property expressed in units of grams per mole (g/mol)īecause the definitions of both the mole and the formula mass are based on the same reference substance, 12C, the molar mass of any compound is numerically equivalent to its formula weight in amu. This calculator is a convenient tool for calculating the molar mass of chemical compounds in lieu of using a periodic table. It has the atomic symbol Co, atomic number 27, and atomic weight 58.93. The periodic table lists the atomic mass of carbon as 12.011 amu the average molar mass of carbonthe mass of 6.022 × 10 23 carbon atomsis therefore 12. A trace element that is a component of vitamin B12. The masses of 1 mole of different compunds, however, are different, since the masses of the individual molecules are drastically different. In each case, the number of grams in 1 mol is the same as the number of atomic mass units that describe the atomic mass, the molecular mass, or the formula mass, respectively. C Add together the masses to give the molecular mass. The molar mass of each element is the same as the atomic mass listed on the periodic table. ![]() ![]() Similar to atoms, 1 mole of any compound contains the same number of molecules as 1 mole of any other compund. B Obtain the atomic masses of each element from the periodic table and multiply the atomic mass of each element by the number of atoms of that element.
