Using the average atomic masses, the mass (in g) of the sample should be determined.

125 moles of lithium

Concept Introduction:

Atomic mass unit measures mass in an atomic scale, it is a standard unit for mass. Here, 1 amu is equal to the mass of either one proton or neutron and equals to 1 g/mol. Atomic mass unit is equal to 1/12^t^h of the mass of C-12 atom. For example, if average atomic mass of carbon is 12.01 thus, it is the mass of 1 carbon atom.

Number of moles = given massMolar mass.
