How many atoms are in 1.75 mol chcl3

1 mol=6.022 * 10²³ (atoms or molecules)
1.75 moles of (CHCl3) we have: 1.75 moles*(6.022 10²³ molecules)=1.05385  10²⁴ molecules.

a molecule of CHCl₃ have, 1 atom of C, 1 atom of H, and 3 atoms of Cl, therefore a molecule of CHCl3 have 1atom+1 atom +3 atom=5 atoms.
Therefore:

1 molecule (CHCl₃)5 atoms
1.058385 10²⁴ molecules (CHCl₃)    x
x=(1.058385  10²⁴ molecules* 5 atoms) / 1 molecule≈5.26925  *10²⁴ atoms.

solution: ≈5.269  10²⁴ atoms.

30litre of li2o is 1.0002mole approximately 1 mole
