Final answer:
To calculate the number of Li atoms in 4.8 mol of Li, we can use Avogadro's number. The number of Li atoms is approximately 2.9 x 10^24 atoms.
Step-by-step explanation:
To calculate the number of Li atoms in 4.8 mol of Li, we can use Avogadro's number, which relates the number of particles in one mole of a substance. Avogadro's number is approximately 6.02 x 1023 particles/mol. To find the number of Li atoms, we multiply the number of moles by Avogadro's number:
Number of Li atoms = 4.8 mol x 6.02 x 1023 atoms/mol
Number of Li atoms = 2.9 x 1024 atoms
