Explanation:

Given parameters:

Number of particles of lithium  = 4.151 x 10²⁵ particles

Unknown:

Number of moles  = ?

Solution:

From the mole concepts, we know that;

         6.02 x 10²³ particles are contained in 1 mole of a substance

          4.151 x 10²⁵ particles contains    = 68.95moles
