The same way one finds any mean by adding up many measurements and dividing by the number of measurements. Or in some problems, by using a percent abundance of each Atomic Mass, though the periodic table deals with this for scientists and displays the average atomic mass below the element.
Lithium is a meta element. Atomic mass of it is 7.
Naturally occurring lithium contains two isotopes. The common one has an atomic mass of 7. About one per cent of the lithium has an atomic mass of 6.The atomic mass of Lithium-Li is 6.941 grams.
The atomic number of lithium is 3. The only stable isotope of lithium has 4 neutrons. Therefore its relative atomic mass is 7.
Lithium is a meta element. Atomic mass of it is 7.
Carbon (12) has a higher atomic mass than lithium (7).
The atomic mass of lithium is 7. The atomic mass of the bromide ion is 80. Therefore the molecular mass is 87u.

The atomic mass of lithium-6 is 6.941 amu
The atomic mass of Lithium(Li) is 6.941g.
Lithium's molar mass is 6.941g/mol. To find the molar mass of an element, take the atomic weight on the periodic table in grams.
Lithium is element #3. That, of course, is the atomic number - the number of protons. The atomic mass will of course depend on the specific isotope. The most common isotope is Lithium-7, that is, atomic mass = 7. Lithium-6 also occurs in nature as a stable isotope.
Carbon (12) has a higher atomic mass than lithium (7).
Lithium is a metal element. Atomic mass of it is 6.941.
The average Atomic Mass of Lithium (Li) is 6.941.
