To solve the problem we will use the following equation:

n (Li) = N (Li) / NA

n - the number of moles

N - the number of particles

NA - Avogadro's number that has following value: 6.022*10²³ mol⁻¹

From the upper relation follows:

N (Li) = n (Li) * NA

N (Li) = 1mole * 6.022*10²³ mol⁻¹ = 6.022*10²³ atoms of lithium
