Mass of Mg=24g
Number of moles in 0.004g=4/24000=1/6000
hence, number of atoms=(6.022*10^23)/6000
=6.022*10^20/6
3.011*10^20/3
10.026*10^19 atoms

no. of moles = given weight / atomic mass
= 0.004/24
= 4/24000
= 1/6000 moles..
no.of atoms = no. of moles x 6 x 10^23
= 1/6 x 6 x 10^20
= 10^20 (approx)
= 0.004/24
= 4/24000
= 1/6000 moles..

= 10^20 (approx)
