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 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.


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 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.


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.


The molar mass of copper, represented by the chemical symbol Cu, is about 63.54 grams per mole. The molar mass is calculated by finding the atomic weight of a substance per mole of the substance.


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 Fe2O3, which is the chemical formula for iron(III) oxide, is 159.68 grams per mole. The molar mass is determined by adding together the atomic weight of each atom in the compound.


The molar mass of KNO3, also known as potassium nitrate, is 101.1 grams per mole. This molecule exists as a single potassium ion and a single nitrate ion held together with an ionic bond.
