Molar mass is the amount of mass in one mole of a substance. A mole is used in chemistry as a counting unit indicating the amount of ions, atoms, molecules or formula units in a specific chemical sample.


The molar mass of carbon monoxide or CO is 28.01 grams per mole. Scientists determine the molar mass of a compound by adding together the atomic mass of each element contained in the molecule. The atomic mass of carbon is 12.01, and the atomic mass of oxygen is 16.


To determine an element's molar mass, it is necessary to add together the weight of all of the atoms present in the sample. The atomic weight of an element is printed inside the element's box on the periodic table. The molar mass is the atomic weight multiplied by the number of atoms per mole.


Ag stands for the chemical element silver, and its molar mass is 107.9 grams. The molar masses of all chemical elements are shown on the periodic table of the elements.


The molar mass of lead is 207.2 grams/mole. The element has an atomic number of 82 and is a solid at room temperature. It can be found in period 6 and group 14 on the periodic table.


Calculate the molar mass of a compound by using the chemical formula of the substance and the atomic weight for each type of atom in the substance. For example, the molar mass of sodium carbonate is 106 grams per mole.


The molar mass of the chemical element iron is 55.845 grams per mole. Iron is represented by the symbol Fe. It is designated with the atomic number 26 on the periodic table.


The molar mass of gold is 196.97 g/mol. To find this number, multiply the atomic mass by the molar mass constant, which is one gram per one mole because gold in its elemental form is a single atom.


The molar mass of aluminum is 26.9 grams/mole. It is in Group 13 on the periodic table and found in Period 3. Aluminum has an atomic number of 13, and it is found on the p-block on the periodic table.


The molar mass of calcium is 40.07 grams per mole, which is the same as the atomic mass of the element. The molar mass is found by determining the mass of a substance present in a single mole.
