Determine the number of atoms in 1.75 mol Al

Question

Help me please :)

Answer 1

1.75 mol Al x 6.02x10²³ atoms/mol = 10.54x10²³ atoms = 1.05x10²⁴ atoms 

Answer 2

in order to solve this one you can multiply by Avogadro's number to convert from the moles to the number of atoms

1.75 mol x (6.022 x 10^23 atoms/mol) = 1.05385 x 10^24 atoms

meaning that there are approximately 1.05 x 10^24 atoms in 1.75 mol of aluminum
