Question

Calculate the number of atoms of 52 moles of Ar.

Answer 1

1 mole of Ar have 6.022×10^23 atoms.

Therefore,
52 moles of Are have atoms
=52×6.022×10^23
=313.144×10^23
=3.13144×10^25

Answer 2

1 mole of Ar contains 6.022 x 1023 atoms of Ar.

It says 52 moles of Ar = 52 x 6.022 x 1023 atoms of Ar will be there.

                                   = 3.131 X 1025 atoms of Ar

this is the way you can Calculate the number of atoms of 52 moles of Ar
