The number of lithium, Li atoms in 4.5 moles of lithium, Li is 2.7×10²⁴ atoms

Data obtained from the question

  • Number of mole of Li = 4 moles
  • Number of atoms =?

Avogadro's hypothesis

1 mole of Li = 6.02×10²³ atoms

How to determine the number of atoms

From Avogadro's hypothesis given above,

1 mole of Li = 6.02×10²³ atoms

Therefore,

4.5 moles of Li = 4.5 × 6.02×10²³

4.5 moles of Li = 2.7×10²⁴ atoms

Thus, we can conclude that 2.7×10²⁴ atoms are present in 4.5 moles of lithium.
