Answer:

68.95moles

Step-by-step 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
(4.151 x 10^(25) )/(6.02 x 10^(23) ) = 68.95moles
