What is the molar mass of lithium?

The molar mass of lithium, represented by the chemical symbol Li, is about 6.94 grams per mole. The molar mass is calculated by finding the atomic weight of a substance per mole of the substance.

The atomic mass for lithium is found on the bottom part of the Li square on the periodic table of elements. The other number, listed on top of the symbol Li, is the atomic number and should not be used to calculate the molar mass of lithium. The molar mass is used as a conversion factor in chemistry to calculate the amount of grams or moles of a substance.
