No of atoms=moles×6.022×10²³(avogadro number)
=0.35×6.022×10²³
=2.10770×10²³ atoms
=0.35×6.022×10²³
=2.10770×10²³ atoms

1 mole = 6.022 × 10^23 atoms
0.35 mole = 6.022 × 10^23 ×0.35
0.35 mole = 2.1077 × 10^23 carbon atoms.
0.35 mole = 6.022 × 10^23 ×0.35
0.35 mole = 2.1077 × 10^23 carbon atoms.

1 mol of copper metal = 6.022 x 1023 atoms of Cu
Therefore 0.35 mol of copper metal = 0.35 x 6.022 x 1023 atoms of Cu
= 2.1 x 1023 atoms of Cu
Therefore 0.35 mol of copper metal = 0.35 x 6.022 x 1023 atoms of Cu
= 2.1 x 1023 atoms of Cu
